Duotone bug causing jarring UI response when selecting custom color

[annezazu]

Description

Apologies for the rough title (feel free to rename) but this was tricky to describe. Essentially, when trying to set a custom color with duotone, the UI starts to break down. This was found during the eleventh FSE Outreach Program call for testing.
