Problem Description

Adding a text block in a container with background image is not accessible. Switching to a light color doesn't help either. Should there be a support for opacity?

Start by reproducing the supplied Card JSON on NodeJS with SDK version 1.3, focusing on the TextBlock inside the background-image Container. Define the expected accessible contrast behavior and whether opacity support is required; done means the text remains accessible in this scenario and the behavior is covered by an appropriate validation.
