MinimumAccelerated2dCanvasSize:
  comment: >-
    Number of pixels below which 2D canvas is rendered in software
    even if hardware acceleration is enabled.
    Hardware acceleration is useful for large canvases where it can avoid the
    pixel bandwidth between the CPU and GPU. But GPU acceleration comes at
    a price - extra back-buffer and texture copy. Small canvases are also
    widely used for stylized fonts. Anti-aliasing text in hardware at that
    scale is generally slower. So below a certain size it is better to
    draw canvas in software.

NeedsDeferKeyDownAndKeyPressTimersUntilNextEditingCommandQuirk:
  comment: >-
    This is an iOS-specific quirk. Unlike Mac, keyboard operations are asynchronous and hence a DOM update as
    a result of text insertion or deletion does not occur within the same event loop iteration as a dispatched
    DOM keydown event. Some sites, notably Google Sheets, schedule timers on keypress and expect on a DOM update
    to have occurred on expiration. When enabled, this quirk puts all such scheduled timers in a holding tank
    until the keyboard performs the insertion or deletion. This gives Google Sheets the illusion that the DOM
    update happened within the same event loop iteration that the keypress event was dispatched in.
