github.com project: folder mentioned in .gitignore is lost on page reload

[cristianbogdan]

Describe the bug

I have a src folder in gitignore, and it is occasionally lost when I reload the ~/github.com/ stackblitz

stackblitz/core#3301

Link to the blitz that caused the error

https://stackblitz.com/~/github.com/kth-csc-iprog/unit-tests?file=package.json&view=editor

Steps to reproduce

1. In stackblitz dashboard, look at github repositories. In my case it is an organization repository: https://stackblitz.com/orgs/github/kth-csc-iprog/repositories
2. Open a repo
3. Add a folder like "src" to .gitignore
4. Commit and push .gitignore
5. drag and drop a folder with that name from the OS desktop
6. reload page. The folder will not show up. It seems to be treated similar to node_modules (which is most often in .gitignore)
7. remove the folder from .gitignore. Commit and push
8. drag and drop a folder with that name from the OS desktop
9. reload page. The folder is now shown, now it is not lost between reloads. Or not always at least

Expected behavior

If the ~/github.com/ blitzes are merely supposed to be "an editor of what's in github" this is probably correct behavior. But this is very confusing because other blitzes do not lose files/folders like that.

Parity with Local

• I have run the project in my local machine and I could not reproduce the issue.

Platform

That's the entire idea of the .gitignore, that it's being ignored. We use that as well to track what we store between page reloads and what not.
