I've got a really weird problem with upfront editor I can't figure out.
On my local development environment (Vagrant + VVV) the menu for the Upfront code editor doesn't appear as shown in screenshot.
I have tried deleting everything and trying on a fresh install and problem remains. I have used exact same code on my live server and the menu appears fine on the live server.
The weird difference is that on my live server I cannot resize the panel. On my local one I can resize it but I cannot see the menu so I cant close it or change to a different tab which makes it impossible to use.
I took a screenshot of each and also made this video to show you that the HTML is the same, the menu does load but it gets pushed down behind the actual editor itself:
Any ideas what is causing this?
