0) Go to https://fullscreen-keyboard-lock.glitch.me. 1) Click "Go fullscreen" button. 2) Click "Show the dialog" button. 3) You're kicked out of fullscreen mode. The app should remain in fullscreen mode.

This seems to be working in recent versions of iOS. I'm closing, but feel free to reopen if you still see the issue.
