Adding a text color or text style preset is broken with inline selection

[barklund]

Bug Description

When in edit mode inside a text field with multiple colors in the given selection, adding a text color or text style preset does not work. Currently the click to add a preset is completely ignored.

Fixing this requires figuring out exactly what should happen in the different possible cases.

This is a known consequence of #1323.

I documented this and put it as WAI for now. We can revisit this and implement some other changes in the future if necessary, but for now, closing as not a priority.
