Show code actions for the problems even when the file is not open

[FMorschel]

Does this issue occur when all extensions are disabled?: Yes

• VS Code Version: 1.96.0
• OS Version: Windows 11 Pro

Steps to Reproduce:

1. Add a file with a "problem" and some server fixes
2. Close that file
3. Restart the cache for the server (close vscode and reopen)
4. You can now have any other file opened here. If you try to right-click the problems it'll only show "Copy" options
5. As soon as you open the file you can right-click on the "problem" and you'll see the list of fixes from the server
6. Now you can close it and whatever (maybe cache or something?) that list will always show

I've asked @DanTup (the maintainer of the Dart-Code extension - for Dart) and he said there are no requests to the server until you open that file.

Is this intended behaviour or a bug?

and he said there are no requests to the server until you open that file.

VS Code doesn't send any requests for diagnostics but it works via push. Extensions should use the tabs api/model to manage their own strategy. Forwarding to @dbaeumer please LSP does something

VS Code doesn't send any requests for diagnostics but it works via push.

This comment referred to the codeActions request, rather than diagnostics. In the bug above, the server pushes diagnostics to VS Code, but when you hover over a diagnostic in the Problems tab, there is no request to CodeActions (to show the lightbulb menu) unless the file is open.

I'm not sure if this is intended or a bug.

I think the title of this issue would be better as "doesn't send requests for Code Actions (Fixes?) unless the file is open".

Thanks for the naming suggestion!
