Adjust container query units for page zoom
rdar://167711217
Reviewed by Brent Fulgham.
Container query units were not adjusted for page zoom when
evaluation-time zoom is enabled, causing elements to overflow their containers.
Viewport units already had this adjustment via adjustValueForPageZoom.
Apply the same zoom adjustment to container query units, except when computing
font-size so that text still scales with page zoom.
User impact: On marketwatch.com, zoomed-in pages caused video captions to
incorrectly display outside video bounds.
