Fix double import breaking all splits

[christopher-besch]

Closes #14

The injected_dependency nodes don't get deleted properly; this has to be fixed before merging.

Thanks for this contribution!
Reloading the import cell does not break the splitview widget anymore, however closing and re-opening the notebook will now make jupyter forget the css and javascript after these pr changes.

Only restarting the kernel of the reopened notebook and running the import brings back the javascirpt+css functionality.

Sounds like a couple of hours wasted...
Maybe a Jupyter Widget makes more sense in the end of you can cleanly add your own CSS and JS.

That's strange; I just tested this on my machine and I can't reproduce the issue...
I added some more debug logs. Could you reopen the notebook and paste the browser console output?

Programs are behaving weirdly from time to time.
Here is the testing with the new version:

Interestingly, the bug does only occur after I re-run the import after reopening the notebook.

And one more important thing to note:
This bug does not occur, when one restarts the kernel before closing the notebook

Ok, I know what the issue is. I'll fix it later today.

Could you try this again, @kolibril13?

[kolibril13]

Thanks for the next update!
With this version, the widget does not show at all, only white space is remaining where the images should be displayed:

No idea how this slipped through the cracks...
Please try again.

Really nice, now everything is working as expected.
Excellent work!

Looks great and does what it should do, thanks a lot for this contribution!

There are two merge conflicts right now,
can you once merge the last main into this branch?
