Problem Description

After PR #13109, the outline explorer populate its content only after a change is made to a file.

It would be great if the content of the outline explorer could be populated for all files that are open on startup.

Thanks @jnsebgosselin for the feedback! @ccordoba12 @andfoy is there something that we can do here?

[andfoy]

Yes, we are aware of this bug, I think this is a problem with the LSP requests, which are being sent before the server is fully initialized. I can add a workaround on PR https://github.com/spyder-ide/spyder/pull/13885 as well

[andfoy]

@jnsebgosselin, do you have any further comments regarding the new outline explorer improvements?

[jnsebgosselin]

No, I think everything else is looking good. Thanks for the work you've done here. I'm glad that the OE was finally migrated to use the LSP, I think this is neat and I hope this will be easier to maintain too.

Dwelling more into this subject, I think this issue is more related to PR https://github.com/spyder-ide/spyder/pull/13828, I don't know what @ccordoba12 thinks about it

Yeah, I think it is. I'll take a look at this problem in that PR.

@andfoy, please don't add a workaround for now (it shouldn't be necessary).

Yes, we think it's going to be much easier to maintain and extend.

@ccordoba12 PR #13938 fixed the problem when starting Spyder, thank you very much!

However, the same problem is still present when switching projects.
