Marking as WontFix, as this was an intentional change made for MD according to Sebastien's spec.

Then I'm going to argue with Sebastien.  This looks really gross.

Moving this nonessential bug to the next milestone.

Sebastian says we can change this as long as the hover region matches the visible paint region and the corners of the selection/hover rects are rounded to match the omnibox.

After discussing with peter, we'll revert to constrained selection with rounded corners to match the omnibox visuals.

I have a local fix for this.

Adjust BackgroundWith1PxBorder corner radius to scale properly.

The ".5" in the existing radius was intended to get to the middle of the stroke,
but that portion of the radius value was in px and not DIP, so scaling the whole
thing wasn't correct.  Instead, set the corner radius to the value of the "inner
radius", then add .5 after scaling.

This fixes a problem where, at larger scale factors, the focus ring's curvature
was slightly different than the edge's curvature.  It also very slightly changes
the appearance of the corner (no one would notice without zooming in).

Update omnibox dropdown selection/hover background drawing for MD.

Rather than use full-window-width selections, return to using omnibox-width
selections, but with a rounded corner to match the omnibox corner shape.

BUG= 612758 
TEST=Type in the omnibox.  The selected dropdown entry should have a selection background the same width as the omnibox, with the same rounded corners.
