Seems like an unrelated issue. The patch in this bug trims the text content tooltip but does not control the tooltip position or rendering, since it's using a HTML `title` attribute. Might be worth reporting as a new bug in the Inspector component, and see if this is related to how DevTools manages its frames (I know we changed that recently and it had a handful of side effects) or if it's a more general Gecko/Windows integration issue.

Note: can't reproduce on macOS, so it might be Windows-specific.
