Expected behavior

Keep emulator card display the same as adaptive card designer.

We may want to transfer this over to Web Chat before addressing in Emulator. (Used the json provided by @DingmaomaoBJTU and see the same behavior in Web Chat)

Sounds like Web Chat should send our new hostconfig over to Adaptive Cards. Could we get this issue transferred to Web Chat?
I think it would be super awesome to do another pass on our hostconfig too.

I sent a message to a rep of the Adaptive Cards team asking that they update their site with our new hostconfig. I haven't heard anything back yet, but I will continue to check-in and report back here. :)

[DingmaomaoBJTU]

Thank you so much!~

I got a response from the Adaptive Card team :) Web Chat is free to do a PR to their repo with the updated host config. Since Adaptive Cards' v.next has a lot of new changes, updating the file will not be trivial. We're keeping this for the 4.5 milestone, but I will work on this at a later date when I can delegate more time to it.

I would still super love to have another Adaptive Cards on Web Chat design pass. @DesignPolice, what do you think?
