Type mismatch reported for interpolated strings with multiple % specifiers in IDE checking #20752
Description
Consider this code:
let flag = true
let s = $"%b{flag} %b{flag}"It compiles fine with fsc, but ParseAndCheckFileInProject reports an error on the string:
Error FS0001 : Type mismatch. Expecting a
'bool -> string'
but given a
'bool -> bool -> string'
The type 'string' does not match the type 'bool -> string'
It happens when there are two or more % specifiers and at least one of them is not a bare %s/%c/%d/%i/%M, i.e. %b, %A, %f or %5d.
This seems to be a regression in #19971. Initially reported as RIDER-143926.
