RTC is adding extra /RTC%3A (colon) after /tree in the notebook URL

Description

Hi. We have jupyterhub instance with RTC extension, and the problem we see that after going to the hub address and click on a notebook, we see that there is /RTC being added to the URL, which messes up with other stuff. Such us anchor links, or git extension. it happens even on the user's own stuff, not when trying to get to other users' stuff.

This is what happens when I watch the URL bar:

2. /user/hnykda/lab/workspaces/auto-y
3. now user clicks on a notebook
4. ends up with: /user/hnykda/lab/workspaces/auto-ytree/RTC%3notebook-name.ipynb

Expected behavior

RTC would not be added to the URL.

Is there any way how to get around this?

Hi @hnykda! The was changed in #418 and the fix can be tested in alpha versions :

pip install --pre "jupyterlab>=4.4.0a2" "jupyter-collaboration>=4.0.0a0"

And if you have Notebook installed:

pip install --pre "notebook>=7.4.0a1" "jupyterlab>=4.4.0a2" "jupyter-collaboration>=4.0.0a0"

For more context see #202. I think we should close this issue?
