A demo of a table caption that causes this bug

If a table has a <caption> element with the CSS rule "position: absolute", VoiceOver cannot read the contents of the table, and gets "stuck".

This mainly occurs when you use the left/right swipe gestures to move the VoiceOver cursor.

It is common to see 'screen reader only' content in websites. This is typically implemented with an '.sr-only' CSS class or similar, such as in Bootstrap.
Most '.sr-only' implementations use the 'position: absolute' CSS rule.
This means, if a content author wants to visually hide a table caption but preserve accessibility for screen readers, this bug will occur - making it impossible to access the table's contents.
