When using VoiceOver, I'm able to send a click event (VO+Space) to an element with the role="combobox" attribute only when it does not have the aria-expanded attribute. Once the attribute is set, regardless of its value, the click action does not work. I'm able to send the click event for comboboxes with aria-expanded in Chrome and Firefox. See the live example of a select only combobox in the ARIA authoring practices- https://www.w3.org/TR/wai-aria-practices-1.2/examples/combobox/combobox-select-only.html If you remove the aria-expanded="false" from the element in the web inspector and try sending the click- it will work- the listbox popup will expand. Some other notes: - it seems that Safari is treating an element with role="combobox" and aria-expanded="false" as if it was expanded as it begins the announcement with the word "confirm", - aria-expanded is a required state as per the ARIA spec (https://www.w3.org/TR/wai-aria-1.1/#combobox) meaning that it must be present at all times - the issue will be highly problematic once ARIA 1.2 turns into a recommendation (currently in candidate recommendation meaning it is close to become the spec) as 1.2 officially acknowledges comboboxes as select-only and text field comboboxes whereas previous versions were treating this element as if it always had to have a text box. Alos, see the attached aria-ExpandedComboboxIssue.html file that shows the issue but displaying the system alert dialog on click. 1843826 1 webkit-bug-importer 2022-02-19 04:20:01 -0800 <rdar://problem/89185237> 1843831 2 aron_j 2022-02-19 04:25:12 -0800 *** This bug has been marked as a duplicate of bug 236881 *** 452635 2022-02-19 04:19:51 -0800 2022-02-19 04:19:51 -0800 Crude test case of the aria-expanded issue ariaExpandedComboboxIssue.html text/html 2771 aron_j PCFET0NUWVBFIGh0bWw+CjxodG1sIGxhbmc9ImVuIj4KPGhlYWQ+CiAgICA8bWV0YSBjaGFyc2V0 PSJVVEYtOCI+CiAgICA8bWV0YSBodHRwLWVxdWl2PSJYLVVBLUNvbXBhdGlibGUiIGNvbnRlbnQ9 IklFPWVkZ2UiPgogICAgPG1ldGEgbmFtZT0idmlld3BvcnQiIGNvbnRlbnQ9IndpZHRoPWRldmlj ZS13aWR0aCwgaW5pdGlhbC1zY2FsZT0xLjAiPgogICAgPHRpdGxlPkNvbWJvYm94IGFuZCBhcmlh LWV4cGFuZGVkIGlzc3VlPC90aXRsZT4KICAgIDxzdHlsZT4KICAgICAgICBrYmQgewogICAgICAg ICAgICBiYWNrZ3JvdW5kLWNvbG9yOiAjZWVlOwogICAgICAgICAgICBib3JkZXItcmFkaXVzOiAz cHg7CiAgICAgICAgICAgIGJvcmRlcjogMXB4IHNvbGlkICNiNGI0YjQ7CiAgICAgICAgICAgIGJv eC1zaGFkb3c6IDAgMXB4IDFweCByZ2JhKDAsIDAsIDAsIC4yKSwgMCAycHggMCAwIHJnYmEoMjU1 LCAyNTUsIDI1NSwgLjcpIGluc2V0OwogICAgICAgICAgICBjb2xvcjogIzMzMzsKICAgICAgICAg ICAgZGlzcGxheTogaW5saW5lLWJsb2NrOwogICAgICAgICAgICBmb250LXNpemU6IC44NWVtOwog ICAgICAgICAgICBmb250LXdlaWdodDogNzAwOwogICAgICAgICAgICBsaW5lLWhlaWdodDogMTsK ICAgICAgICAgICAgcGFkZGluZzogMnB4IDRweDsKICAgICAgICAgICAgd2hpdGUtc3BhY2U6IG5v d3JhcDsKICAgICAgICB9CiAgICAgICAgY29kZSB7CiAgICAgICAgICAgIGNvbG9yOiAjMDM2Owog ICAgICAgICAgICBmb250LXdlaWdodDogNzAwOwogICAgICAgIH0KICAgIDwvc3R5bGU+CjwvaGVh ZD4KPGJvZHk+CiAgICA8aDE+Vm9pY2VPdmVyIGNsaWNrIGRvZXMgbm90IHdvcmsgb24gY29tYm9i b3hlcyB3aXRoIGFyaWEtZXhwYW5kZWQ8L2gxPgoKICAgIDxwPlRlc3QgY2FzZSBkZXNjcmlwdGlv bjo8L3A+CiAgICA8dWw+CiAgICAgICAgPGxpPgogICAgICAgICAgICBFYWNoIGNsaWNrIGV2ZW50 IHNob3VsZCB0cmlnZ2VyIHRoZSA8Y29kZT5hbGVydCgpPC9jb2RlPiBtZXRob2QgYW5kIGNoYW5n ZSB0aGUgdmFsdWUgb2YgdGhlIDxjb2RlPmFyaWEtZXhwYW5kZWQ8L2NvZGU+IGF0dHJpYnV0ZSBv ciBzZXQgPGNvZGU+YXJpYS1leHBhbmRlZDwvY29kZT4gaWYgbm90IHByZXNlbnQuCiAgICAgICAg PC9saT4KICAgICAgICA8bGk+CiAgICAgICAgICAgIEluaXRpYWxseSwgdGhlIHNlY29uZCA8Y29k ZT4mbHQ7YnV0dG9uJmd0OzwvY29kZT5lbGVtZW50IHdpdGggPGNvZGU+cm9sZT0iY29tYm9ib3gi PC9jb2RlPiBjYW4gYmUgYWN0aXZhdGVkIHVzaW5nIDxrYmQ+Vk8gKyBTcGFjZTwva2JkPi4KICAg ICAgICA8L2xpPgogICAgICAgIDxsaT4KICAgICAgICAgICAgT25jZSB0aGUgPGNvZGU+YXJpYS1l eHBhbmRlZDwvY29kZT4gaXMgc2V0IG9uIHRoZSBjb21ib2JveCB0aGUgPGtiZD5WTyArIFNwYWNl PC9rYmQ+IGNsaWNrIGV2ZW50IGlzIGJsb2NrZWQgaW4gU2FmYXJpICh3b3JrcyBpbiBDaHJvbWUg YW5kIEZpcmVmb3gpLgogICAgICAgIDwvbGk+CiAgICA8L3VsPgoKICAgIDxkaXY+CiAgICAgICAg PGJ1dHRvbj4KICAgICAgICAgICAgQWxlcnQgMQogICAgICAgIDwvYnV0dG9uPgogICAgPC9kaXY+ CgoKICAgIDxkaXY+CiAgICAgICAgPGxhYmVsIGZvcj0iY29tYm8iPkFsZXJ0IDI8L2xhYmVsPgog ICAgICAgIDxidXR0b24gaWQ9ImNvbWJvIiByb2xlPSJjb21ib2JveCI+Tm8gb3B0aW9uczwvYnV0 dG9uPgogICAgPC9kaXY+CgoKICAgIDxkaXY+CiAgICAgICAgPGJ1dHRvbj5BbGVydCAzPC9idXR0 b24+CiAgICA8L2Rpdj4KCgoKICAgIDxzY3JpcHQ+CiAgICAgICAgY29uc3QgYnV0dG9ucyA9IEFy cmF5LmZyb20oZG9jdW1lbnQucXVlcnlTZWxlY3RvckFsbCgnYnV0dG9uJykpOwoKICAgICAgICBj bGFzcyBBcmlhRXhwYW5kZWRJc3N1ZSB7CiAgICAgICAgICAgIGNvbnN0cnVjdG9yKG5vZGUpIHsK ICAgICAgICAgICAgICAgIHRoaXMubm9kZSA9IG5vZGU7CiAgICAgICAgICAgICAgICB0aGlzLmFk ZENsaWNrRXZlbnQoKTsKICAgICAgICAgICAgfQogICAgICAgICAgICBhZGRDbGlja0V2ZW50KCkg ewogICAgICAgICAgICAgICAgdGhpcy5ub2RlLmFkZEV2ZW50TGlzdGVuZXIoJ2NsaWNrJywgdGhp cy5oYW5kbGVDbGljay5iaW5kKHRoaXMpKTsKICAgICAgICAgICAgfQogICAgICAgICAgICBoYW5k bGVDbGljaygpIHsKICAgICAgICAgICAgICAgIGFsZXJ0KHRoaXMubm9kZS50ZXh0Q29udGVudCk7 CgogICAgICAgICAgICAgICAgaWYgKHRoaXMubm9kZS5nZXRBdHRyaWJ1dGUoJ2FyaWEtZXhwYW5k ZWQnKSA9PT0gJ3RydWUnKSB7CiAgICAgICAgICAgICAgICAgICAgdGhpcy5ub2RlLnNldEF0dHJp YnV0ZSgnYXJpYS1leHBhbmRlZCcsICdmYWxzZScpOwogICAgICAgICAgICAgICAgfSBlbHNlIHsK ICAgICAgICAgICAgICAgICAgICB0aGlzLm5vZGUuc2V0QXR0cmlidXRlKCdhcmlhLWV4cGFuZGVk JywgJ3RydWUnKTsKICAgICAgICAgICAgICAgIH0KCiAgICAgICAgICAgICAgICB0aGlzLm5vZGUu Zm9jdXMoKTsKICAgICAgICAgICAgfQogICAgICAgIH0KICAgICAgICBjb25zdCBpbnRpYWxpc2Ug PSBmdW5jdGlvbigpIHsKICAgICAgICAgICAgYnV0dG9ucy5mb3JFYWNoKGVsID0+IHsKICAgICAg ICAgICAgICAgIG5ldyBBcmlhRXhwYW5kZWRJc3N1ZShlbCk7CiAgICAgICAgICAgIH0pCiAgICAg ICAgfQoKICAgICAgICB3aW5kb3cuYWRkRXZlbnRMaXN0ZW5lcignbG9hZCcsIGludGlhbGlzZSk7 CiAgICA8L3NjcmlwdD4KICAgIAo8L2JvZHk+CjwvaHRtbD4=
