Steps to reproduce the bug

• Upgrade from 2.3.1 to 3.0.0 or 3.0.1
• Use latest Firefox with latest Vue devtools extension

Expected behavior

• Console log for installed stores
• Pinia tab in devtool

Actual behavior

• No '... store installed' messages in the console
• No 'pinia' tab in devtools

No errors anywhere, but simply no dev integration for pinia.

Additional information

Everything else works, the stores work and my app still functions the same, only the development integration is broken.

This might have something to do with the upgrade to Vue Devtool v7? Not sure if that also includes the console statements.

For now, I cannot upgrade to 3.0.x.
