Mattermost Version: 5.8.0-rc1
Database Schema Version: 5.8.0
Steps to reproduce:
1. Launch MM (make sure it has multiple servers configured including community daily, but make sure community daily is not the first tab)
2. Wait for the first load animation to complete, then immediately flip to another server tab
VIEW VIDEO FOR REFERENCE (it happens from 11 seconds to 14 seconds in the video)
as the new tab loads, the internal window size is a tiny div that then gets resized and you can see this as a user, we need to fix this.
