When creating a Pull Request in a Fork repository the default target branch is from the original repository.
Example:
I have a repository "main-repo" with "master" and "feature1" branches.
I forked this repository into "repo-fork-1".
If I go to the "feature1" branch in the "repo-fork-1" and enter in the "compare" view, it shows the diff between this branch (as source) and the "master" branch in original repository "main-repo" (as target). If I press then "Create Pull Request", the Pull Request is created in the target repository.
Even I can change this before creating the Pull Request, one can easily create the Pull Request for the wrong target branch (i.e., the same branch name but in the wrong repository), since it's not expected that it will choose the original repository as default. In my opinion this is wrong.
Is there already an issue opened for this?
