Show HN: A js library to create and manage highly customizable modal windows

The "press escape to clear textbox and again to close the modal" example doesn't seem to be working for me (vivaldi 1.11.901.3 (64-bit) on Windows 10), it just closes the modal on the first press.

Will test other browsers.

Edit: Works in Chrome (59.0.3071.115) and Firefox (54.0.1), must just be a Vivaldi quirk - they're always breaking something.
