Load https://files.paciellogroup.com/blogmisc/ARIA/slider/ 2. With VO on, select the slider thumb. 3. Double-tap and hold (wait for the tone if applicable) and drag left or right. Results: Text selection UI (with drag handles) appears. Expected: VO pass-through drag should change the position of the slider thumb, resulting in the web app changing the aria-valuenow attribute, which then VoiceOver should announce. Similar to the expectation for native sliders... 1741021 1 webkit-bug-importer 2021-03-17 20:51:01 -0700 <rdar://problem/75558315> 1741226 2 jcraig 2021-03-18 09:40:50 -0700 Update: Paciello example doesn't support touch events. That might do explain it... If confirmed, this could be closed.
