Fixed
- HDR video looked washed out on macOS with Zia on (#561). To blur the page behind its
see-through surfaces, Zia had Zen draw the page itself rather than hand it to macOS,
and drawn that way an HDR video loses its HDR. Zia now does that only while something
see-through is over the page (the address pop-up, a hover card, the find bar, the
compact sidebar, the swipe arrow, the screenshot buttons), so videos keep their HDR the
rest of the time. Thanks kcussiefil for tracking it down. - The address bar's pop-up is dark in a dark theme and light in a light one (#562). It
went by the light or dark setting for web pages, so a dark theme on a light system got
a white pop-up, and Zen's new-tab bar with it. For the pop-up in your theme's own
colour, turn on "The pop-up takes the toolbar's colour as it opens".
