There are hyperlinks in the mouse title. The user cannot click on it, because the mouse title disapper when the coursor moves to the text.
The text of link is difficult to read: dark grey font color on black background.
no links in the mouse title.
Thanks for creating this issue. Having links in tooltips indeed doesn't make much sense. In this case I guess the description is used that is also displayed on the system check page.
Guess we likely won't change that, as we otherwise would need new tooltip descriptions for each system check item, which would cause a lot new translations being needed. But we maybe could remove the
<a> tags in this case.
