Description Daniel Lu 2021-07-28 16:41:42 PDT 
In iOS 14.7.1, content associated with a table header via aria-describedby are not being announced by VoiceOver. Tapping on the column header or navigating to the header via swipe operations result in VoiceOver announcing the text of the column, the column/row index, etc but just not the aria-describedby content. 

See https://xyi4e.csb.app/ to reproduce:
Repro Steps:
1. Turn on VoiceOver and navigate to the link in Safari in you iPhone/iPad.
2. Navigate to the "Date" column header via tapping on it or swipe commands.
3. Note that VoiceOver doesn't announce "test description" even though that div is associated with the header via aria-describedby.

Note: This works on macOS 14 + VoiceOver + Safari 14
