💻 Code

Happens in a large codebase, I am currently unable to reproduce. The new error appears when a complex mapped & conditional type is used

🙁 Actual behavior

Multiple new: error TS2589: Type instantiation is excessively deep and possibly infinite.

🙂 Expected behavior

Type checks successfully as in 4.2

Note

I bisected and found that this PR is introducing this break. While the behavior outlined there seems to be a net improvement, maybe a solution that doesn't break existing types can be found? Or if not this should be outlined in the 4.3 release notes as a breaking change.
