Typecase disables Customize x-out link

I’m enjoying this plugin’s integration with Twenty-Fifteen.
One annoying bug if you could fix with the next upgrade.
Typecase when activated will make it so when you are in customizer window the X in the top left to exit Customize and return to the dashboard, is disabled.

I’ve tried it in the recent versions of Safari and Firefox. I’ve toggled on and off Typecase and for sure it’s this plugin that is the source.

More annoying than a deal-breaker, hope it’s an easy fix.
