Subject: [PATCH] Add regression test for i19675 (#21159)

Originally fixed by #19926
Closes #19675

Even though this is a slower sbt scripted test, I think it's worth
adding, since it showcases a different issue than what #19926 was
fixing, and I do not believe it is reproducible in any way without a
scala-2 dependency (so we cannot minimize it into regular compilation
test).
