VoiceOverBug
Issue: TableView UI in a weird state when VoiceOver is enabled.
Description: When a table view has a very long cell (greater than device height), VoiceOver scrolls result in a state where the cell is not visible at all.
Steps to reproduce
The following steps were performed on a iPhone X, iOS 13.2
-
Run the application and observe that there is one cell with a red background color in a table view which has a green background color
-
Turn on voice over
-
With the accessibility focus on the cell, swipe left. The cell disappears from the view hierarchy. (Red view is gone.) Confirm this in the view hierarchy debugger.
-
Sometimes a combination of left/right swipes are needed to reproduce the issue.
When the issue is observed, the following assertion is seen in the debugger:
