Running debug build clang-format with `-debug` parameter against code provided in #56350 (and its duplicate #58469) you see `Penalty for line: 10000`. So pretty obvious the [severe penalty](https://github.com/llvm/llvm-project/blob/703e83611cd8bb7174ae76ba2e301f5a5e88b905/clang/lib/Format/FormatToken.cpp#L140) is responsible. 

Thoughts on this change? Is the removal of the severe penalty being applied too broadly? ... or is it correct/OK?
