Andoid App - Tinker Mode - Tinkered color disappears when switching to a default color.

Steps to reproduce

• Edit a text element
• Use Tinker mode to change the color
• When you finish Tinkering, the tinkered color appears as selected in the color list
• Select another color
• What happens - The tinkered color disappears as an option
• Expected - The tinkered option should stick around, so I can use it again (possibly even in other elements!)
