Inconsistent tab/shift-tab behavior with form elements

[ecronin]

tabbing between form elements in the forward direction will stop at the last element. shift-tabbing in the reverse direction will loop around. option-tab and shift-option-tab are even stranger, stopping at the end in the forward direction and tabbing right out of the browser window window in the reverse direction, losing text focus and requiring a click before tab-* works again.

I have run into some tabbing issues as well, but typically for me it has been due to how the form elements are coded. Do you have an example?

www.gmail.com (the login screen) was where I first noticed it, www.yahoo.com displays the tab/shift-tab behavior as well. textareas seem to alter the behavior (so for example this reply to thread page I'm on right now can't be shift-tabbed beyond the message field)
