Allow language server hovers to be displayed while in a debug session

[DanTup]

When debugging, hovering over a class name sends the request to the debugger for evaluation, and not to the language server. This is a bit awkward if you want to read the documentation for a type that's in the code you're debugging.

This was briefly discussed at #48747 (comment) but I was asked about it again and it looks like there's no open issue tracking it.

This seems like really useful functionality - even if Code can't render multiple tooltips, being able to hold down a modifier or something to get the language tooltip while debugging would be nice.

For now forwarding to @weinand as he looked into debug adapter language server integration and might have more details

True, VS has the same limitation.

@isidorn I like the idea of using a modifier key to switch between debug hover and language hover.
This approach does not need any additional integration between debug and language services.

Special case of #102939?

[isidorn]

I also like that idea. Let me assign to September so I can investigate more then.

Let's close as dup of #84561
Thanks @Trass3r for pointing out
