SPFx extension CommandSet in document library appears multiple times in context menu

Describe the bug

After deploying an SPFx extension with location ClientSideExtension.ListViewCommandSet.ContextMenu or ClientSideExtension.ListViewCommandSet the command randomly appears multiple times in the context menu. After a Shift-Reload the command always appears correctly.
This behavior is unrelated to the form of deployment. It's happening with tenant wide deployed extensions as well as with site controlled deployments.

The actual control is always fired only once, even when it appears twice ore more often. It seems so be a caching issue when the page renders.

Steps to reproduce

DELETE THIS LINE BEFORE SUBMITTING - Provide steps to reproduce the behavior:

1. Create a SPFx Extention
2. Set in elements.xml location="ClientSideExtension.ListViewCommandSet" and ListTemplateId="101"
3. Deploy to app catalog and add to site
4. (especially in nested folders?) the context menu entry appears twice or more often
5. Shift-reload the page to clear the multiple entry

Expected behavior

The command should only appear once.

Environment details (development & target environment)

• Target Environment: SharePoint Online
• Framework: SPFx v1.11.0
• Browser(s): all Browsers

Is there any update on this issue? We've seen the command rendering up to ten times in the context menu and will not be able to release our extension in this state.

More and more of our customers complain about this issue. Is any chance to get an estimate of when it might be resolved, please?

Hi @Marlen-Jacob - sorry for the long delay. Is it still an issue for you? I'm unable to reproduce the issue using the steps you provided.
@AntoninaSavka - could you please provide me a sample command set where you experience the issue?
Or could you check if the one below has the same issue on your tenant(s)?

@AJIXuMuK I work with @AntoninaSavka and I've tested the attached sample on our tenant and it does not have the same issue but I've created a minimal sample extension that reproduces the issue, attached here. The main difference is that this has a RegistrationId of 101 so that it works on document libraries.

It doesn't immediately show multiple times but after you navigate around the SharePoint tenant a bit, it will start appearing multiple times and from then on it is rare to see a command appear only once in the context menu.

Hi @danwalshnitro - thank you for the sample. I will investigate it.

Hi @AJIXuMuK Thank you for your reply! It is still an issue and I can confirm it occurs on document libraries.

Best regards,
Marlen
