After clicking on the horizontal navigation arrow in the quick answer area, if you don't click anything else and move the cursor away we get this behavior:
- The CLICKED arrow doesn't disappear (still visible)
- The other arrow disappears (becomes invisible)
For better understanding I am including this screenshot:

And forgot to add that the change in styleSet doesn't affect these arrows
ANOTHER BUG:
Another bug (that is included in version: "botframework-webchat": "^4.2.1-master.0dffd85",) is that the actions have quotes around them (you can notice them on the picture above) , while I am receiving them without quotes from directLine (checked in the json that I received).
BTW: I know that 4.2.1 is not official yet, but 4.2.0 is too broken for my implementation, sry.
