Issue autocomplete not working on edit MR

Summary

Cannot search issues when editing an MR step through the autocomplete mechanism.

Steps to reproduce

Create an MR
Go to edit the MR
Try to link to an issue by typing #
See the loading spinner go forever

Example Project

I have not tested this on gitlab.com

What is the current bug behavior?

The issue autocomplete ajax never fires, and the loading box never goes away

What is the expected correct behavior?

A list of issues should show up, similar to the way it does when commenting or creating an MR

Relevant logs and/or screenshots
