Reminder to disallow switching to a tab with display:none in tabBindings.xml in the future (once you can properly check style through the dom).
Blake, didn't you at some point create a fix for this? I can swear I reviewed it a while back.
I made one to ignore hidden="true". I couldn't get display: none working because there's a problem with getComputedStyle not returning the right property value.
Is getComputedStyle working for this now? There have been a number of fixes for it recently.
