Question: How to contribute patches for version 136.0.7103.113?

[RecursionTaoist]

I've prepared a patch for version 136.0.7103.113 that fixes linker errors related to ungoogled_switches.

The issue was that several build targets were missing the required dependency. The patch adds "//components/ungoogled:ungoogled_switches" to the deps section in the following BUILD.gn files:

• //components/embedder_support/BUILD.gn
• //third_party/blink/common/BUILD.gn
• //third_party/blink/renderer/core/BUILD.gn

However, I encountered a problem when trying to submit a Pull Request. GitHub shows the error: "There isn’t anything to compare. main and my-branch are entirely different commit histories."

Could you please advise on the correct workflow to contribute patches for a specific version tag like 136.0.7103.113? Should I attach the patch file to an issue instead, or is there a different branch I should target for such fixes?

Thank you for your guidance and for maintaining this project!
