Don't resize tabs until mouseout

When you close a tab the remaining tabs resize instantly. This is different from Chrome's behaviour which waits until the mouse is away from the tab bar. The benefit is that it is easier to remove multiple tabs without having to move the mouse.

I experience an immediate change in width when the tab is closed. The effect should be similar though.

It is immediate but it would be better to wait until mouseout to be more like chrome.
