fix(invert): Avoid spurious LOK invalidations

Using the same mechanism as with theme changes, we can avoid LOK getting
invalidations if we have an invert-background change that doesn't apply.

The trouble is that this method of inverting the background causes *lots
of* properties to change, so there's no single "If we inverted the
background" to check...

To get there, I've checked if all of the following are true
- We didn't change the color scheme
- We didn't have any new colors after this change
- All of the properties we were changing should have been within this
color scheme

While they don't necessarily mean "there was a background inversion",
they do mean "something changed in your theme but no action is needed
from you" - which should only be a background inversion - and if we
added anything else that could fit in that category, it should also
avoid LOK invalidations
