Merge Request: Recover switching from Inline and Parallel diff modes without reloading the page
In order to fix https://gitlab.com/gitlab-org/gitlab-ce/issues/48666 in time for release of 11.1, we resorted to changing pages when switching between Inline and Parallel diff modes.
It's obviously not ideal, so we'll recover this asap using Vue.
This page is being remodelled with performance in mind but some architectural changes will potentially benefit the end result, which allow for better switching of modes.
This however, takes time that we don't have until the next RC or the feature freeze on the 7th. I'm putting milestone 11.2, but if sooner, even better.
