in the history view of the popup window, the titles of videos are truncated - that's good. however, when the mouse hovers over them, the full title should appear as a tooltip.
popup/popup.html: added :title="videoHistory.title" to the .history-video-title div (line ~210) alongside the existing x-text="videoHistory.title". Since videoHistory.title already holds the untruncated string (truncation is purely visual via text-overflow: ellipsis in popup/popup.css), binding the native title attribute to the same property gives the browser's default tooltip with the full text on hover — no new computed property needed.verify-csp skill: the new binding is a plain property reference (no expressions, comparisons, or method calls), so it's CSP-compliant. Confirmed the only existing CSP violation in the file (x-show="videos.length === 0", line 195) is pre-existing and unrelated to this change.
