SUMMARY
Sometimes a semantic analysis note/action/highlight will appear at the end of a line of code. For example, edit a function declaration and an "Adapt Signature" highlight will appear at the end of the line. If you hover over the line, a popup will appear - in this example, it will have a clickable link to apply the action. I'm finding that if you hover over the highlighted part that starts at the text's end-of-line, and the KDevelop window is small enough that the popup has to shift to the left, then moving the mouse immediately resets the popup - making it impossible to click anything in the popup.

This only seems to happen for the past-end-of-line highlight part and only when the popup has to shift to stay within the KDevelop window bound - all other cases (hover over the text, or window is wider) seem to keep the popup open when the mouse is moved, allowing the user to click any links therein.

I attach some images that hopefully illustrate the issue. In particular, compare fine3 (wider window) with buggy (narrower window). In the former the popup stays with ample time to move the mouse into it for clicking any links, while in the latter, the popup disappears as soon as the mouse moves.

Peace,
