Deadlock in Scala 3 version of MiMa when analyzing scala 3 code #867
Description
After updating mill-mima to Scala 3 we noticed mimaReportBinaryIssues hanging.
This happens only when you use the Scala 3 artifact of mima-core and analyzing a Scala 3 library.
It seems to be related to changes in lazy val initialization in Scala 3.
