@akshika898 , can you add before pictures?

This will lead to another accessibility issue since now table headers won't be announced as table headers.

[akshika898]

Did this way as we do not have an option to give indicators in headers. Adding * as text was not a very good way and it would be shown in black which will be different from other indicators in extension leading to inconsistency in UI.
I understand that the header is now defined as row but even in previous version the tab did not go to headers, neither the narrator defined specifically for headers, nor I found error in accessibility insights. Do we have any other way to test it?

[akshika898]

As discussed, merging this as a temporary fix.
