3.5 causing major jQuery and JavaScript errors

I have a site where 3.5 is causing some really bizarre jQuery errors.

I am developing a site here:
https://ally2.alchemycs.com

On the home page, in the middle where it says “Screenings,” there is a box with scrollbars. The site should be using jScrollPane to make the scrollbars match the design of the rest of the site. It worked fine before 3.5, but when I upgraded to 3.5, it broke and jScrollPane no longer works. Now I get an error message:
Error: Permission denied to access property 'toString'
This error message is caused by the embedded Vimeo video. If I take that out, I get a new error message:
Error: Syntax error, unrecognized expression: [type="text/javascript"],not([type])
That message is caused by modernizr.js, so if I disable that, I get a new error message:
Error: Syntax error, unrecognized expression: [type="text/javascript"],not([type])
It says that this error occurs in line 2 of jquery.min.js, which is being served by Google, so I know it doesn’t have errors in it.

In 3.4.2, this doesn’t happen. In 3.5, it does. Disabling all of the plugins doesn’t fix it.

Any suggestions for what to do next?
