Cannot click/open a dropdown merge button in merge requests
Problem
Originally reported by @Jamesking56 at https://gitlab.com/gitlab-org/gitlab-ce/issues/64948#note_194665269
Generally, when you click the "Merge when pipeline succeeds" dropdown button, you'll see two buttons under the dropdown - 1. Merge When Pipeline Succeeds 2. Merge Immediately
However, a user reported that this dropdown is not functional and emit an error message in JS console.
