cause is jline/jline3#862 , so we may need to move to JLine 3.25.1 in order to fix it 😕

At least it's specific to 11! Doesn't happen on 8, 17, or 21.

Also the REPL seems to work fine anyway, at least as far as I can tell — I've added “harmless” to the issue title, hopefully I won't have to remove it again 🤞

@SethTisue FYI: Scala 3 has been updated to used JLine 3.25.1 (in scala/scala3#19744)
