F-string formatting adds unnecessary space after ** operator

[dhruvmanila]

Consider the following source code:

f"aaaaaaaaaaaaaaaaaaaaaaaaaa {10**27} bbbbbbbbbbbbbbbbbbbbbbbbbb ccccccccccccccccccccccccc"

Running ruff format --preview:

f"aaaaaaaaaaaaaaaaaaaaaaaaaa {10** 27} bbbbbbbbbbbbbbbbbbbbbbbbbb ccccccccccccccccccccccccc"

Huh, that's weird

[MichaReiser]

Oh, is it because of the inner group and the entire line exceeds the line length. We might need to remove if_group_breaks from RemoveSoftLinesBuffer

this could be annoying

Yeah, and we use RemoveSoftLinesBuffer but that doesn't remove the space as you've mentioned.
