Describe the bug / error

In my company we are using the ListView Command Set to display commands both in the command bar and in the context menu. Suddenly the commands in the context menu (ECB) are not visible anymore in a client production environment without any updates of our SPPKG file.

Using Yeoman generator I've created a sample solution based on the default template for the ListView Command Set extension. Then changed the custom action location to ClientSideExtension.ListViewCommandSet and run gulp serve. The commands does show up in the command bar but does not display in the context menu, I've tried it even in another tenant with no luck.

Updating the custom action location to either ClientSideExtension.ListViewCommandSet.ContextMenu or ClientSideExtension.ListViewCommandSet.CommandBar seems to have no consequence, the commands still show up in the command bar, no matter what value we provide for location, and not in the context menu.

Steps to reproduce

1. Create a new SPFx solution (v. 1.20.0) for a ListView Command Set
2. Change the location of the commands to ClientSideExtension.ListViewCommandSet
3. Execute gulp serve
4. The commands are present in the command bar but not in the context menu

Expected behavior

I would expect the SPFx extension to keep working as before. When specifying the location as ClientSideExtension.ListViewCommandSet the commands should be displayed in both the command bar and the context menu as stated in the Microsoft learn documentation.

If needed here is the repo with the code I've used.

@reedpamsft & @natalieethell - Seems that we have a highly impactful issue on dropping again SPFx menu items from the context menu. Something which will for sure impact wide range of customers if this is in progress to rollout.

Thanks for reporting! We've identified the fix and will have it rolled out by February 24th.

The rollout of the new UI in DocLibs will not continue until this fix is out.

Thanks for the update @natalieethell!

Sorry, *the week of February 24th. Likely early in the week as long as build rollout goes as planned!
