I think I may have found a solution for the problem.
File: assets/js/signdoc.js
In the makeSignatureKeyboardAccessible() function, when checking if the keypress code == 13 (i.e. is the return / enter key), check to see if the keypress was made inside of a textarea. If it was, then do not call signaturePopup.click();
I've created a gist with my changes. The gist includes the code that starts on line 631 of the signdoc.js file.

It would be nice if this (or some form of this) could be incorporated into the plugin so that my changes aren't lost after applying plugin updates.
