x/exp/shiny: panic is not panicky #13963
Description
go version devel +c5a2f36 Thu Jan 14 20:57:21 2016 +0000 darwin/amd64
Once a window has been initialized, any panics (either by calling panic() or some other means) do not exit the program or print a stack trace, but rather cause the program to hang. If the window has been published, the cursor becomes a spinning beachball.
