/* Safari does not paint a freshly loaded document while a closed popover carries
   `position-try-fallbacks`. The document loads and lays out correctly, but nothing reaches the screen
   until a hover changes a computed style; the sidebar's user menu is a popover, so every page is
   affected. Fallbacks only mean anything once a popover is open, so limiting them to that state
   keeps flipping where it is used. Confirmed on Safari 26.5.2 and 26.6 — retest on later versions and
   remove this when Safari paints without it. */
