User Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10.11; rv:48.0) Gecko/20100101 Firefox/48.0
Build ID: 20160630123429

Steps to reproduce:

Go to this page: https://learnzillion.com/lzui#modals
1) Scroll down to click the button to launch the standard modal
2) Close the modal
3) Click the button to launch the modal without title/footer
4) Interact with the input field within the modal

Video (not exact steps): http://recordit.co/qJC6RILdNm


Actual results:

Interacting with the input field will not display a caret, and text will not be highlighted when selected.


Expected results:

The input field has a caret indicator where the mouse is, and any selected text is highlighted.  Note: when only opening the modal without title/footer, this happens as expected.  Opening a second modal, breaks inputs not only on the modal, but anywhere on the page (if present).
I can reproduce this issue on: 	Mozilla/5.0 (Macintosh; Intel Mac OS X 10.11; rv:50.0) Gecko/20100101 Firefox/50.0.
Tested on other browsers and it works as expected.

It's been broken for as far back as Firefox 6 (Firefox 5 didn't render the page correctly, so I couldn't test).
