Button to add review comment on MR is unreachable using keyboard
Summary
The button used to add a comment when reviewing code on a merge request is unreachable with the keyboard
Steps to reproduce
- Go to any merge request
- Go to changes (
/diffs) - Try to reach a button that adds a review comment ("Add a comment to this line") using the keyboard, i.e. pressing the
<Tab>key
What is the current bug behavior?
It's unreachable, because such buttons are shown only when the related line is moused over
What is the expected correct behavior?
Buttons to add review comments should be reachable with the keyboard.
Output of checks
This bug happens on GitLab.com
Possible fixes
The button could be invisible but present, so that when it's reached by tab-nabigating, it gets visible, similar as when mouse-overing a line.
