JetBrains: Monaco editor does not shrink when context gets longer

Created by: philipp-spiess

When we change the context dropdown to a larger string, the icons on the side of the editor gets pushed outside of the viewport. Strangely enough the selecting a smaller string will properly re-layout the editor.

This behavior works on sourcegraph.com so it must be something with our own flex rules but I can't easily figure out what it is so I’m postponing this with an issue :(

There's special logic in Monaco to re-layout the editor when the container element changes dimensions. This callback is run in our case yet the width does not properly calculate.
