Edit Pull Request : Visible label/ form field are not associated

Issue Summary

The "Description" input field for edit pull requests has a missing explicit association.

Element: Description edit field
Location: Just below the Description toolbar.

Steps to Reproduce

1. Launch the URL
2. Navigate to the "Show more pull request actions" button present on the right top of the page and activate it and select "Edit".
3. Once the modal to edit the pull request is available navigate to the "Description" input field area.

Actual Results

The "Description" input field for edit pull requests does not have a label explicitly associated with it. The 'for' and 'id' association is missing between the label and the 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.
