Image Display Color not working with Matrix Object in b26

I encountered a problem using Image Display Objects in a Matrix in b26 which works properly in b25.
I use the image display object to display a color based on the result of a formula. This is not working in b26. A fixed color in the formula works.

Running b25 and b26 in Mojave. Anyone else encountering this problem?

This was reported about 2 weeks ago.

TLDR; the problem is fixed in the upcoming b27 release.
