## Summary This PR stabilizies the fix for https://github.com/astral-sh/ruff/issues/14001 We try to only make breaking formatting changes once a year. However, the plan was to release this fix as part of Ruff 0.9 but I somehow missed it when promoting all other formatter changes. I think it's worth making an exception here considering that this is a bug fix, it improves readability, and it should be rare (very few files in a single project). Our version policy explicitly allows breaking formatter changes in any minor release and the idea of only making breaking formatter changes once a year is mainly to avoid multiple releases throughout the year that introduce large formatter changes Closes https://github.com/astral-sh/ruff/issues/14001 ## Test Plan Updated snapshot |

Ruff Formatter
The Ruff formatter is an extremely fast Python code formatter that ships as part of the ruff
CLI.
Goals
The formatter is designed to be a drop-in replacement for Black, but with an excessive focus on performance and direct integration with Ruff.
Specifically, the formatter is intended to emit near-identical output when run over Black-formatted code. When run over extensive Black-formatted projects like Django and Zulip, > 99.9% of lines are formatted identically. When migrating an existing project from Black to Ruff, you should expect to see a few differences on the margins, but the vast majority of your code should be unchanged.
If you identify deviations in your project, spot-check them against the intentional deviations enumerated below, as well as the unintentional deviations filed in the issue tracker. If you've identified a new deviation, please file an issue.
When run over non-Black-formatted code, the formatter makes some different decisions than Black, and so more deviations should be expected, especially around the treatment of end-of-line comments. For details, see Style Guide.
