Steps to reproduce the issue

Go to any screen which has a help screen, for example Content -> Articles.
Click on the text "Help" of the help toolbar button and you will see the appropriate help screen. However, if you click on the question mark to the left of the text you will get a much larger blank window with "about:blank" in the address bar.

Expected result

Clicking anywhere on the help button (even on the question mark) should open the appropriate help screen.

Actual result

The help screen only opens if the user clicks on the text of the help button.

System information (as much as possible)

Chrome on Ubuntu 22.04.
php 8.1
Joomla 4.4.2 and Joomla 5.0.2 (same behaviour on both).
