Browser / Version: Firefox 102.0
Operating System: Linux
Tested Another Browser: Yes Chrome

Problem type: Something else
Description: Access key gives focus but does not press the button
Steps to Reproduce:

1. Open the URL: a textarea has focus.
2. Press Alt+Shift+D: “Skip” button (with d accessKey) is pressed. The first textarea is hidden, another one displays.
3. Press Alt+Shift+D again.

On Chromium (expected): the second textarea is hidden, the third one displays.

On Firefox (issue): focus is given to “Skip” button, but it is not pressed down.

Note I believe it used to work in Firefox 78.
