I've had the same experience! Well sort of, I think it's related to the experimental zoom I enabled. Trying to track down how to reproduce so I can open a bug,

  I've possibly figured it out. If you scroll quickly and while the inertia carries the scrolling onwards hit ctrl+w to close the tab, it'll resize the next tab that gains focus. Presumably that's because ctrl is held down and it's scrolling, even though the scrolling is only from inertia. Obviously scrolling shouldn't carry over to the new tab, so it does look like a bug. Moreover, it also resizes the website of the tab you just closed. Guess I need to submit a bug report. Edit: apparently Bugzilla requires passwords longer than 10 characters - wow! At least the that's the error I got (password too short) when I tried to sign up. Seems excessive.
