Description of this change

Opening Bazel project corrupts status bar widgets

[tpasternak]

I know it's been a while, but it seems that the issue is not reproducible any more with IJ 2022.2

Hello @avshenuk, Did you get a chance to verify the issue in the latest release as mentioned here https://github.com/bazelbuild/intellij/pull/2150#issuecomment-1213209743

[avshenuk]

@sgowroji Yes, the status bar is not broken anymore. Thank you!

So the only feature this PR adds now is a modal dialogue asking which window the project should be opened in (current or new, as with regular projects). But you can close it if you think it's not worth it.

Right, let's take it then!
