UI Tests check is failing on CI
Opening a new issue since the check is failing on the latest commit on master: https://github.com/widgetti/ipyvolume/commit/1c08f9fdde4219be873f7c45e02ecec2540d5876

Opening the report shows some differences with the UI elements:

Not sure if this was introduced in a previous PR, but probably updating the reference snapshots should help fix it.
Also the UI Tests setup could be updated to use a more recent @jupyterlab/galata based on Playwright: https://github.com/jupyterlab/jupyterlab/tree/master/galata
For example:
- https://github.com/voila-dashboards/voila/tree/main/ui-tests
- https://github.com/jupyter-widgets/ipyleaflet/tree/master/ui-tests
Upgrading to the newer setup would also allow for integrations like automated snapshots updates with a bot: https://github.com/jupyterlab/maintainer-tools#update-snapshots
Partially fixed in https://github.com/widgetti/ipyvolume/pull/424 (not yet upgraded, will keep that in mind!)
