MR wrongly claims that "source branch does not exist"

Summary

MR claims that "source branch does not exist" but displays the diff and commits just fine

Steps to reproduce

  1. Fork a project
  2. push a new branch onto the fork
  3. create a MR merging the new branch into master

Example Project

Not able to reproduce on GitLab.com yet

What is the current bug behavior?

The "Merge" button is gray, and says "source branch does not exist. Please restore it or use a different source branch"

What is the expected correct behavior?

The "Merge" button should be clickable and working.
