KeyEvent crashes on macOS.

[ccqpein]

I am developing my app with druid and find the KeyEvent will crush my app. I thought I missed something so I run example/event_viewer with cargo run --example=event_viewer. It still crashes, but only happened when I don't select the interactive_area.

So, the behaviors are:

1. run cargo run --example=event_viewer in my shell
2. event_viewer window shows
   a. I click any keys now and app crashed
   b. I click interactive_area and press the keys. app runs normally.

My env:

• macos 11.2.3
• Intel CPU
• rustc 1.53.0-nightly (07e0e2ec2 2021-03-24)

Is this on master? I can't reproduce on macOS 10.15.7, but very possible something changed in big sur.

Yes, it is, I test it after pull master.

Could this be related to #1711? Does it still happen with the multiwin example (which explicitly sets a menu)?

I feel it might related with #1711 ; And yes, it happens.
