const enum MyVer { v1 = 1, v2 = 2 }
let ver = 21
const a = ver < (MyVer.v1 >= MyVer.v2 ? MyVer.v1 : MyVer.v2)🙁 Actual behavior
It reports error TS1005:
R:/working/a.ts:4:27 - error TS1005: ')' expected.
4 const a = ver < (MyVer.v1 >= MyVer.v2 ? MyVer.v1 : MyVer.v2)
~
R:/working/a.ts:4:60 - error TS1005: ',' expected.
4 const a = ver < (MyVer.v1 >= MyVer.v2 ? MyVer.v1 : MyVer.v2)
~
Found 2 errors in the same file, starting at: R:/working/a.ts:4
🙂 Expected behavior
The part between ( and ) should be parsed as an operand of <.

Most likely another side-effect from #47607.
