After T269297 and T269295 are fixed, the primary performance issue remaining with page previews is the creation of SVG on the fly in order to clip the image.
This can be replaced with a much simpler clip-path, however clip-path is not supported on IE11 and non-Blink Edge browsers (non modern supported in browser support matrix).
