+1 -- I am able to reproduce this issue.
Appears to be fixed in JupyterLab v4.1.2 onwards. Selectors for ArrowRight and ArrowLeft are now more specific ".jp-Notebook.jp-mod-commandMode:not(.jp-mod-readWrite) :focus" instead of just ".jp-Notebook:focus.jp-mod-commandMode" and are no longer triggered within RISE.
Recommendation is to update to the latest version of JupyterLab.
Description
When a slide with fragments is reached, pressing the right arrow key on the keyboard will not reveal any fragments. If the right or down arrow is pressed enough times, the slideshow will just advance to the next slide.
If the left arrow is pressed to go to a previous slide with fragments, it will sometimes show a button that says "+ n cells hidden" which when clicked will allow fragments to be shown as they should (sequentially as the right or down arrow is pressed).
Edit: Upon further inspection, could this be caused by a conflict with JupyterLab's key bindings below?
Update: It appears that right and left arrow keys work for showing fragments when I disable the above bindings that collapse and expand headings.
Reproduce
Expected behavior
On a slide with fragments, fragments should be revealed one by one as right arrow key is pressed and disappear one by one as left arrow key is pressed.
