This is actually an Dotty bug.

[pjfanning]

This also affects the 1.0.x branch - i.e this is not a new issue

[He-Pin]

as it's not going to be fixed in scala 3, so we should change the code then :)
refs: scala/scala3#19803

[pjfanning]

@He-Pin any idea what a change would look like and whether it would be possible to get it into 1.1.0-M1?

[He-Pin]

@pjfanning Yes, I'm fixing it locally, I was expected Scala 3.3.3 fix this.
