/*
 * CSP fallback styles.
 *
 * Inline style="" attributes were moved to data-style="" and are re-applied via
 * CSSOM by csp-handlers.js (style="" is blocked once 'unsafe-inline' is removed
 * from the style-src CSP directive). That re-application happens just after the
 * element is parsed, which would let elements that should start hidden flash
 * visible for a frame. This rule hides them immediately at parse time, before
 * the JavaScript runs.
