I know you did. You even mentioned this. But, where is the original?
I am also mentioning about another bug on the same lines from someone else too. (#11) If I “report” this one on Yaru-dark, the result would be the same. So, please report it yourself. You have Ubuntu Eoan so you can reproduce it, I suppose.
It appears that Ubuntu doesn’t know what it has as system extensions (at least one), who actually maintains it (and why). The thinking behind it is given in his blog (in Spanish) and in Git Lab page.
“The extension ID is supposed to be unique.” says @jbicha. True enough, but can carry any name, and that name is not a bug. Best always is to reproduce the matter and see.
