When you select multiple text objects and attempt to change their color based on a binding, only the first selected text object actually gets said binding.

How to reproduce:

• Open 2D View, create multiple text objects.
• Select each of them individually with ctrl+click
• Go to properties --> multiselection --> text color and click on set binding in dropdown
• Make their colors based on some condition (e.g. radiobutton.checked ? "blue" : "black" )
• Notice when its applied that only the first object receives the binding
