WKWebView crashes if user answers an incoming iMessage

My apps have a significant crash -

CALayer position contains NaN: [377.833 nan] 

with the following stack -

Looking at the logs of the users I found few common things -

1. All of the users are in a view controller that contains a WKWebView
2. All the logs point that the app got "applicationWillResignActive" before the crash
3. The stack shows that a keyboard was opened, but we do not have away to open the keyboard on that View Controller
4. all users are iOS 10.3 +

The only scenario that fit was that a user got an iMessage while the app was with a visible WKWebView and force touched it to a quick answer. We tested this scenario and BOOOM the app crashed.

So we found the crash, but we do not have a clue what is going on. Any one faced that issue or has an idea what could it be?

Thanks
