The mask overlay (x-pw-glass) is shown via the popover API, which places it in the top layer and gives it a ::backdrop pseudo-element. A broad page rule targeting ::backdrop bled onto it and tinted the whole viewport during masked screenshots (regression since 1.59). Neutralize it from a document-level stylesheet, since the host ::backdrop is unreachable from the glass pane shadow root. Fixes: microsoft#41504
