Failed to import - material ui tabs no longer working

[schlichtanders]

It is not a module failing, but a module not working correctly.

A few days ago the Tabs and TabList from material ui (mui) worked normally, now all versions of material ui I tried won't show the tablist anylonger.
This looks like the recent esm module compilation may have kicked out significant parts of the code which it hasn't before.
That is quite tough, meaning one cannot rely on esm based modules. Still it would be nice to get this fixed.
Is there a workaround? the pin does not seem to exist any longer, does it?
