Witout preventDefault all works fine. 1078518 1 graouts 2015-03-19 05:11:45 -0700 I just ran into this issue today, where this works fine in Firefox, but fails in Safari and Chrome. Since the original URL no longer seems to work, I've attached a testcase where commenting out the call to `event.preventDefault()` in the `mousedown` event handler shows that mouse events are dispatched even when outside the iframe bounds. 1078519 2 249033 graouts 2015-03-19 05:12:26 -0700 Created attachment 249033 Testcase 1078520 3 249034 graouts 2015-03-19 05:12:44 -0700 Created attachment 249034 Additional testcase content 1078521 4 graouts 2015-03-19 05:26:29 -0700 Raised a Chromium bug too at https://code.google.com/p/chromium/issues/detail?id=468730. 1228155 5 ddkilzer 2016-09-09 09:45:24 -0700 <rdar://problem/28226827> 1503200 6 lforschler 2019-02-06 09:18:35 -0800 Mass move bugs into the DOM component. 249033 2015-03-19 05:12:26 -0700 2015-03-19 05:12:26 -0700 Testcase iframe-event-capture.html text/html 154 graouts PCFET0NUWVBFIGh0bWw+CjxodG1sPgo8Ym9keSBzdHlsZT0iYmFja2dyb3VuZC1jb2xvcjogYmxh Y2siPgogICAgPGlmcmFtZSBzcmM9ImlmcmFtZS5odG1sIiBzdHlsZT0id2lkdGg6IDQwMHB4OyBo ZWlnaHQ6IDMwMHB4OyI+PC9pZnJhbWU+CjwvYm9keT4KPC9odG1sPg== 249034 2015-03-19 05:12:44 -0700 2015-03-19 05:12:44 -0700 Additional testcase content iframe.html text/html 981 graouts PCFET0NUWVBFIGh0bWw+CjxodG1sPgo8aGVhZD4KPHNjcmlwdCB0eXBlPSJ0ZXh0L2phdmFzY3Jp cHQiPgogICAgCiAgICB3aW5kb3cuYWRkRXZlbnRMaXN0ZW5lcigiRE9NQ29udGVudExvYWRlZCIs IGZ1bmN0aW9uKGV2ZW50KSB7CiAgICAgICAgZG9jdW1lbnQuYm9keS5hZGRFdmVudExpc3RlbmVy KCJtb3VzZWRvd24iLCBtb3VzZWRvd24pOwogICAgfSk7CiAgICAKICAgIGZ1bmN0aW9uIG1vdXNl ZG93bihldmVudCkgewogICAgICAgIGNvbnNvbGUubG9nKCJtb3VzZWRvd24iKTsKICAgICAgICB3 aW5kb3cuYWRkRXZlbnRMaXN0ZW5lcigibW91c2Vtb3ZlIiwgbW91c2Vtb3ZlKTsKICAgICAgICB3 aW5kb3cuYWRkRXZlbnRMaXN0ZW5lcigibW91c2V1cCIsIG1vdXNldXApOwoKICAgICAgICAvLyBU aGlzIGNhdXNlcyBtb3VzZW1vdmUgYW5kIG1vdXNldXAgZXZlbnRzIHRvIG5vdCBiZQogICAgICAg IC8vIGRpc3BhdGNoZWQgaWYgb2NjdXJpbmcgb3V0c2lkZSBvZiB0aGUgaWZyYW1lCiAgICAgICAg ZXZlbnQucHJldmVudERlZmF1bHQoKTsKICAgIH0KCiAgICBmdW5jdGlvbiBtb3VzZW1vdmUoZXZl bnQpIHsKICAgICAgICBjb25zb2xlLmxvZygibW91c2Vtb3ZlIiwgZXZlbnQucGFnZVgsIGV2ZW50 LnBhZ2VZKTsKICAgIH0KCiAgICBmdW5jdGlvbiBtb3VzZXVwKGV2ZW50KSB7CiAgICAgICAgY29u c29sZS5sb2coIm1vdXNldXAiKTsKICAgICAgICB3aW5kb3cucmVtb3ZlRXZlbnRMaXN0ZW5lcigi bW91c2Vtb3ZlIiwgbW91c2Vtb3ZlKTsKICAgICAgICB3aW5kb3cucmVtb3ZlRXZlbnRMaXN0ZW5l cigibW91c2V1cCIsIG1vdXNldXApOwogICAgfQogICAgCjwvc2NyaXB0Pgo8L2hlYWQ+Cjxib2R5 Pgo8ZGl2IHN0eWxlPSJwb3NpdGlvbjogYWJzb2x1dGU7IHRvcDogMDsgbGVmdDogMDsgd2lkdGg6 IDEwMCU7IGhlaWdodDogMTAwJTsgYmFja2dyb3VuZC1jb2xvcjogZ3JlZW47Ij48L2Rpdj4KPC9i b2R5Pgo8L2h0bWw+
