Hovering an editor tab with a long path showed a tooltip whose text ran past the bubble: tooltips never wrapped (`white-space: nowrap`) and were capped at 360px.
Tooltip text now wraps inside the bubble, breaking long paths where needed, and the shortcut stays on one line next to it. The bubble grows up to 720px or the window width less 32px, so most paths still fit on one line. Short tooltips look as before (same size and line height), and newlines in tooltip text are still collapsed.
Fixes#968.
