Issue Summary

On the "View pull request" page, the focus does not remain on the activated element.

Steps to Reproduce

1. Navigate onto the above mentioned page.
2. Navigate onto the "2 open tasks" button and activate it.
3. Navigate onto the "Resolve task" checkbox with a screen reader and activate it.
4. Observe that screen reader focus does not remain on the activated element.
5. Observe that the screen reader focus is lost in the background.

Screen recording

Actual Results

When the "Resolve task" checkbox is activated with a screen reader, the screen reader focus is lost somewhere in the background. It does not remain on the activated element. This may particularly disadvantage screen reader users. That the focus is getting lost and the background content is found with virtual arrow keys may confuse or mislead them.

Expected Results

In this case, make sure that focus remains on the element when it is activated. This is the standard behaviour of a checkbox. Make sure that there is no scripting that is moving focus. As well, make sure that the element is not being temporarily removed from the DOM.

Workaround

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