1950687 - Notify the user when hovering out of scope variables

Status: NEW

(DevTools :: Debugger, enhancement)

Description

[Alexandre Poirot [:ochameau]]

When hovering a variable while the debugger is paused, we never know why some variable would show or not show a preview tooltip.
In most cases, that's because the token is out of the paused scope and we actually know that when processing the mouse events.
It would be helpful to surface this information to the user so that the preview tooltips feel more reliable.
