Upstream branch name not respected when pushing

• Build: 2102

Description

So I have a repository which is forked and locally I have main for the original repo, and I created a main-fork from the forked repo.
I wanted to then push main-fork to the remote fork with the branch name main.
I had done "Set upstream..." to the main branch. But then when I push it just ignores that and creates a fork-main branch on the fork remote.

You can see here that git says the upstream is set correctly:

$ git branch -vv
* fork-main ae848a4 [fork/main: ahead 6] Merge branch 'main' into fork-main

but it still pushes to fork/fork-main

Steps to reproduce

Steps to reproduce the behavior:

1. Open a repository.
2. Add a new remote called fork
3. Make sure you have a local branch called main which tracks origin/main
4. Now create a new local branch from fork/main called fork-main
5. Check git -vv to make sure it indicates fork/main is the upstream. If not go to submlime merge and right click fork-main and use Set Upstream... to set it to fork/main and then check again
6. Now just hit the push button (you don't need to make any commits to fork-main at all, it will still create fork/fork-main`)

Expected behavior

I would expect it to push to fork/main, but instead it creates fork/fork-main and pushes it there
