### Basic information Steps to Reproduce: 1. Turn on `resistFingerprinting` to make Apple show the fancy product pages on Firefox. 2. Scroll around one of the pages for the new apple product announcements: https://www.apple.com/ipad-air/ https://www.apple.com/mac-studio/. Expected Results: Experience is a 60FPS butter. Actual Results: The scrolling is quite smooth during the first part of the profile where I'm scrolling through regular page. The framerate(?) tanks when scrolling through the page with the ipads animating in. The poor performance is particularly noticeable when large parts of the page are being animated at once. When smaller elements are being animated, the performance is more satisfactory. --- ### Performance recording (profile) Profile URL: https://share.firefox.dev/3Ks2Qs9.
