[Opera 12] responsive menu can't be closed
Created by: ixti
Steps to reproduce
- Open http://twitter.github.com/bootstrap/base-css.html in Opera 12
- Make browse window small to see the responsive menu
- Click the menu button
- Click the menu button again
Expected
Responsive menu should hide away.
Actual result
Responsive menu stays on the page always opened.
Additionally
Looks like the first click on the menu throws an unhandled exception (fired from inside of Sizzle), which stops any further JS execution, unless you explicitly click continue in the developer console.
