Sure, added in f78949a07e33017a798c410a102c95455685a9b1

That does looks odd - I can reproduce it with normal (language-level) typedefs too (rather than with template aliases): https://godbolt.org/z/GsGKqhKzz. I can open a separate issue?

Now that I think about it, I recall @CarlosAlbertoEnciso running into something similar a while ago... I'm sure a bug was filed about something similar but I can't find it. Does this ring any bells @CarlosAlbertoEnciso?
