Description

After setting color options for a nested block, the parent block seems to start showing the color contrast warning, even if none exist. I am still working out the circumstances for when this happens but have narrowed it down to at least one flow.

Step-by-step reproduction instructions

1. Add a query loop block.
2. Change the colors of the post title block within it.
3. Notice that the color contrast warning appears when selecting the overall query loop block.
