Actual Results

The "Commit selector" input in the diff section of the pull request does not have a label explicitly associated with it. The 'for' and 'id' association is missing between the label and the input form control.

Labels need to be explicitly associated with their respective form controls for assistive technologies to identify the label accurately and convey the information to the users.

Expected Results

Associate the label explicitly with the form control by providing an identical value that is unique from other IDs to "for" and "id" attributes to ensure that assistive technologies identify the label for the form control correctly. 

Workaround

Currently, there is no known workaround for this behaviour. A workaround will be added here when available.
