Problem Description

I am currently writing an python module in a spyder project. The __init__.py files classes aren't shown in the outline. I am not able to find any error message in the debug output.
If I rename the file to test.py, the outline immediately shows the classes as intended. After renaming the file back to __init__.py the outline doesn't show any classes again.
Outside a spyder project the outline works for the file. When I open the file in a different project it doesn't work.

After testing the things above I closed the project - and the outline didn't work, even after reopening the file.

I am therefore not able to postulate a rule when the problem occurs. It seems like it is more likely to occur within spyprojects.

Update 1

When looking at some code in the spyder repository I had this issue with other files as well. One didn't work even after renaming, the outline showed its loading animation. Another file worked after placing the cursor inside the linked line.

What is the expected output? What do you see instead?

I see:

I expect something like that:

I have the same problem. When looking at an __init__.py file in the editor, the outline pane does not display any variables, functions, or classes. Special comments "# ----" and cells "# %%" do still appear in the outline, but cell hierarchy is flattened ("# %%%" does not appear nested beneath "# %%" in the outline). Using Spyder 5.0.1, Python 3.8.5 64-bit, Qt 5.9.7, PyQt5 5.9.2, Windows 10

[real-yfprojects]

I am able to reproduce the problem on the same machine but reliable even with the newest main version of Spyder (6.0.0.dev0 - Revision 474057d).

1. I cloned this repository and switched to the develop branch.
2. I created a new project from the existing repository directory.
3. I opened this file called __init__.py.

The outline shows this.

4. I closed the project in spyder.
5. I opened the file again.

The outline now shows this.

If I knew how to talk to the pyls manually, I could inspect further which fault it is.
