I made a gist in case anyone comes along later and needs to copy our code until Elliot can implement an official fix.

Note to regular users out there, you will need to re-compile input.min.js from input.js to take advantage of this fix without enabling debugging. input.js is not loaded by default unless script debugging is enabled with the flag outlined in acf.php. To enable script debugging, you can add define('SCRIPT_DEBUG' , true); to the top of acf.php in the root of the plugin folder.
