extend-expect expect is not defined

[dmvjs]

I get the following error (running playwright, using this dependency) and I don't see expect imported in the src file. Is it expected to be ok as-is or is there a known workaround?

I'm adding the new playwright "component tests" to a repo that already has playwright testing that works fine. It appears to happen as a result of calling the mount method used for component testing.

I see that elsewhere in the code (in tests) describe(), expect(), test() are assumed to be available without being imported.

ReferenceError: expect is not defined
