[macOS] vrbo.com: black color extension shows up after searching for homes
for the first time

Reviewed by Abrar Rahman Protyasha.
Make another small adjustment to the color sampling heuristic — leverage the
ability to blend the
sampled fixed color against the background color of the page (added in
298351@main) to avoid
clamping sampled colors with lighter opacity to opaque colors (with a threshold
of 0.75). This
prevents a solid black bar from appearing behind the navigation bar, when the
top sampled color is a
color like 40% transparent black (i.e. the background color of the background
behind the popup after
searching for homes for the first time on vrbo.com).

Add a second layout test for this color blending heuristic that bypasses the
modal dimming view
detection, but whose opacity is low enough that the resulting sampled color
should not be clamped to
solid black.
