feat(invert): Allow inverted background on init

Previously for Online there was no way to save the background invert
state and reload it. Worse, when someone changed the state it would
become the default for new document loads.

This patch allows Online to specify whether it wants the background to
be inverted, which should allow smooth tab refreshes while also avoiding
mingling state from different people.

There is a change to online to support this here:
