What is the expected behavior?
Tabbing into an <object> tag ought to tab in and then out. But Chrome (on both Mac and Win) seems to get stuck right on it.

What went wrong?
Tabbing through fields works fine but if there is an <object> tag on the page its focus gets stuck. When I've used OS X's VoiceOver I noticed that Chrome thinks it enters a frame and then can't leave the frame.

Does it occur on multiple sites: Yes

Is it a problem with a plugin? No 

Did this work before? N/A 

Does this work in other browsers? Yes
