Found a bug: I have a container for Facebook (and only Facebook) that is set to "limit to designated sites". When I open a new tab and go to instagram.com, the browser gets stuck in an endless loop of opening the tab automatically in the Facebook container, closing it (because it's not facebook.com), opening it in a regular tab, and then closing it (because it thinks it should be opened in the Facebook container). Please fix.

Addendum: Please add support for manually rearranging the list of containers. Thanks!
