running vue-tsc with 1.7 takes 5min instead of 1.5min

[Fuzzyma]

I recently updated from vue-tsc v1.2 to the prereleased 1.7 and my ci went up from only 1.5min to a whopping 5min.

Since since is surely not by design, I wonder what changed that makes it so slow and if that is expected.

I will update this ticket with a more narrow version constraint to see with which version it got so slow

// EDIT:
The time increase happens from version 1.5 to version 1.5.1.

These are the changes made between the versions:
v1.5.0...v1.5.1
