Does not work as expected with unsquashed email patches

[Former user]

When using a patch file containing several patches like GitHub / GitLab produce on Merge Requests when appending a ".patch" to the URL, only the first commit is applied. I'm not sure how this is called correctly.

The expected result would be to apply the whole patch with all commits.

Workaround: Use plain diff patch by adding ".diff" to the URL instead of ".patch" but I guess this should be fixed anyway to make both work.

Example: Doesn't work as expected: https://git.drupalcode.org/project/etracker/-/merge_requests/9.patch Works as expected: https://git.drupalcode.org/project/etracker/-/merge_requests/9.diff
