Conditionals Failing Since Joomla! 3.5.0 Upgrade

Sorry - thought I had this figured out, but I don't. Turns out DJ-ImageSlider wasn't to blame. It was just the most visible element to break on the front end when I renamed the chosen.js files. And as you pointed out, it broke elements of the back end.

I know this isn't a CB problem, but I'm at a loss and hoping you can suggest some hints on how to figure it out.

- I tried grep all the .php files on my site for "chosen.jquery.js". Nothing found (but not a big surprise).
- Grepped for "chosen." (added a period). Found the following:
* /administrator/components/com_admin/views/profile/tmpl/edit.php
* /administrator/components/com_templates/views/style/tmpl/edit_options.php
* /components/com_config/view/templates/tmpl/default_options.php
* /components/com_joomgallery/models/favourites.php
* /layouts/joomla/html/formbehavior/ajaxchosen.php
* /layouts/joomla/html/formbehavior/chosen.php
* /libraries/cms/html/number.php
These are Joomla core files with the exception of favourites.php, and all that had was a comment with the word "chosen" at the end ("// The list of favourites is filtered now, so that only valid images are chosen.").
- I set up a new instance of Joomla and installed all of my components and plugins one at a time until they were all installed (I might have missed some minor plugins), but I couldn't get it to fail.

Any recommendations on how to determine what is loading Chosen?

Thanks

It would have to be a 3rd party extension doing it or the template. Chosen by default doesn't load on the frontend and doesn't load with such an aggressive jQuery selector in backend either. I've no idea what you've installed that's doing this and the only way to find out is to just disable 3 party extensions 1 by 1 until it resolves.
