Inspect Editor Tokens - hover stays open

[aeschli]

Testing microsoft/vscode#89392

Firefox, Shadow Dom

• Run the Inspect Editor Token command
• I wasn't able to hide the hover, Escape or setting focus to an element outside the editor didn't work

This is unrelate to shadow dom, we simply don't have a way to close that at this time.

@alexdima How exactly would we want to close the hover? Personally, I only want it closed when it gets in the way of the text around what I am looking at. So I would only want it hidden until I click onto the next token. What are your thoughts?
Here is how I have it modified currently. When pressing escape, I set visibility = hidden. On the widget compute, I set the visibility = inherit. (I could also just add another listener, but wasn't really sure if that was necessary.)

I just looked in vscode and it has the similar inspect tokens feature, so I think we should setup Monaco the same way.

Escape closes the hover until you select it from the menu again.
