Description

Splits from this thread:
#8065 (comment)

The code should be fixed properly when there are multiple fixes on the same line.
In the repro code, the fix should actually be

typeTest=|string|(((()=>void)))|string;

And in the thread, it should've been fixed regardless of me adding space as a workaround
(you can see that I've changed it from${'a'}${'b'} to${'a'} ${'b'})

Opened adraft PR to start an investigation.
Seems like there are some actual wrong fixes in the tests.
