What steps will reproduce the problem?
1. Open up approximately fifteen tabs.
2. Go to tab on the far left. Hover mouse over the "x" to close the tab.
3. Close the tab. Don't move your mouse.
4. Note that the mouse is nicely placed over the "x" for the next tab.
5. Close that one, if you like!
6. Close enough so that you can see the tabs start to dynamically resize.
7. Once resizing has started, don't close the next tab. Instead, click the space bar once. Chrome should scroll.
8. Note that the tab has now resized and your mouse is no longer over the "x"



What is the expected result?
The expected result is that the tab size stays the same until the mouse is moved. When I have a bunch of tabs open, I'll often hover the mouse over the "x" and keep clicking to close them all. Some sites have pretty large title bars, though, so I need to hit the space bar once or twice to see if I'm missing anything.

What happens instead of that?
When the tab resizes, it means that if I hit spacebar once, I can no longer go through all the tabs quickly. Instead, I need to refocus the mouse for the next tab. There would be no usability regression to just have the tab stay put until the mouse moves.
