b.prop is undefined JS error from WatchJS crashing entire page

I’m getting this constant JS error in console saying “b.prop is undefined”:

What ends up happening is you get that error multiple times a second, until eventually it crashes the entire page or entire browser.

I debugged this myself and tracked it down to the WatchJS minimized code you have in `ap_functions.js` on line #470.

I could not figure out if it was a compatibility issue with my theme, or what the actual cause was … as when I replaced the minimized code you have in your file, with the unminimized code from:

https://raw.githubusercontent.com/melanke/Watch.JS/master/src/watch.js

And now it works fine … not sure what would cause this but certainly was a huge issue for me.
