Summary

Autofix fix for ISC003 (Explicitly concatenated string should be implicitly concatenated) produces TypeError: 'str' object is not callable in the following situation.

result = "Line1\n" + (
    "Line2\n"
    "Line3"
)

ruff check --fix produces:

result = "Line1\n" (
    "Line2\n"
    "Line3"
)

Which gives a TypeError: 'str' object is not callable error obiously.
