Issue description

When I add a list view command set extension to a site it works just fine in the default list views, but it has suddenly stopped working when you embed a list view in a SitePage. This worked earlier on December 22nd 2024, but suddenly the list view command set is not loading now. None of the default list command bar buttons also show up. The network tab shows no trace of the files associated with the command set and the console does not show any related errors.

There are no difference if I gulp serve the files or just load them from the app catalog - no trace of the files trying to load.

The view is configured with "Show command bar" and the command bar does not show the default list view buttons like Edit in grid view, Share, Export to Excel, Copy link and Delete buttons also. It also does not show the list view command set buttons.

This is tested with the command set extension hello-world example: https://learn.microsoft.com/en-us/sharepoint/dev/spfx/extensions/get-started/building-simple-cmdset-with-dialog-api

Steps followed -
Install a command set extension and ensure that it loads in a normal list view.
Embed a list view in a sitepage and observe that the list view command set does not load.
