Invalid ARIA attributes

Thanks, moving over to Gin for the fix!

Test status -Fail
ARAI Issue is reproduceable. But , patch is showing an error.
Tested this using the tool -http://aka.ms/AccessibilityInsights on edit basic page.

@asawari from the image it seemed like you tested the MR on issue page , not on local setup.

I checked MR 569. Looks fine so moving it to RTBC.

Thanks for working on this! I left a question and a minor code suggestion

Hello, I have tested the MR on local on Gin Theme version 4.0.x, and its working as expected .
Added before and after screenshots for reference.

@saschaeggi do you want to review the new code from @batigolix? @snehal-chibde, thanks for the screenshots with the improvement.
