Webview2 crashes at closing if JAWS is running #964

I'm the responsible developer for the Webview2 integration in the commercial software "SAP Business Client". If JAWS is running and the user closes one of multiple open tabs each hosting a Webview2 web browser control, the msedge.exe browser process crashes with exception code 0x80000003, so all open Webview2 instances are lost, not just the one that should actually be disposed. The crash doesn't always occur when closing a Webview2, but with a pretty high chance of about 30%. If JAWS isn't running, everything is fine.
The Webview2 crash actually writes a dump in the crash pad folder of the Webview2 user data folder. I'm attaching it to this report. Please analyze it and fix the issue.
