Layer scope not working for >=3.1.0 #35
Description
Description
When wanting to create a slide background, as I have seen in the Layers.ipynb of https://jupyterlab-deck.readthedocs.io/en/stable/_static/lab/index.html, selecting the layer scope is unresponsive to me.
This dialogue opens, but selecting any of the values is unresponsive. Sometimes the selected value appears for a frame, but disappears then. Adding and saving the value manually to the cell metadata, in the 'advanced tools' section below, does not fix the issue.
"slideshow": {
"slide_type": "",
"layer": "deck"
},Presenting the slides shows the cell as a normal cell.
The same holds true when trying to use the Design Tools from within the presenting mode.
Opening the original Layers.ipynb, without changing any cell metadata also fails to show the cell as a background layer.
Reproduce
To isolate other issues, I have created a fresh environment and only installed jupyterlab-slideshow.
micromamba env create -n debug -c conda-forge python
micromamba activate debug
pip install jupyterlab-slideshow
jupyter labCreating a new notebook, and opening the 'common tools' in the Property Inspector sidebar.
Try to change the Layer value.
Expected behavior
When selecting a value in the drop-down, I expect to see the value change and the cell to be in the background of the slide, for the case of "deck".
Context
- Operating System and version: Linux 6.8.0-52-generic #53~22.04.1-Ubuntu SMP PREEMPT_DYNAMIC Wed Jan 15 19:18:46 UTC 2 x86_64 GNU/Linux
- Browser and version: Firefox 136.0 (mozilla-deb 1.0)
- JupyterLab version: 4.5.0a0
- jupyterlab-slideshow version(s): all
0.3.1-0.3.3(0.3.0 works as expected!)
The JS console did not seem to output anything when changing the selection. The only suspicion I have is the output "Unknown pseudo-class or pseudo-element ‘-ms-input-placeholder’. Ruleset ignored due to bad selector. lab:124:26".
