Slash command not working when using default merge request template setting
Summary
When I add a default merge request template with a slash command /assign @mark-veenstra
in it to ayto-assign the merge request to an user, the slash command is not executed, but displayed in the issue description.
When opening a merge request manually and add a /assign @mark-veenstra
in it, it does auto-assign the merge request. Only problem is the default template doesn't.
Steps to reproduce
Add the following merge request default template to Settings
--> General
--> Merge request settings
--> Default description template for merge requests
/assign @mark-veenstra
This is the default template, for testing auto-assign
Now open an new issue and press the Create merge request
button in the UI. It will create a new branch and a merge request with the WIP status. Only the merge request is not assigned to the user added in the slash command.
