Target Platforms

Android

SDK Version

3.8.3

Problem Description

For the below AC json, a gray area shows below text due to the emphasis container padding. No item shows because the only item is invisible. Can we hide the container if no visible items in it?

Start with the Android rendering path for Container and its isVisible handling, then reproduce the supplied Adaptive Card JSON. The fix is done when a container containing only invisible items does not render its emphasis padding or leave a gray area below the visible TextBlock.
