It may be worth a simple `if (window.IntersectionObserver)` check around (or as an early return in) `lazyLoadImages` so we don't throw an error if it's not supported. > Websites/webkit.org/ChangeLog:-101 > - I don't think we normally go back and edit ChangeLog entries, no matter how "bad" they may be. > Websites/webkit.org/wp-content/themes/webkit/scripts/global.js:-2 > - var openClass = ' open-menu', A comment explaining why this isn't needed would be nice :) > Websites/webkit.org/wp-content/themes/webkit/scripts/global.js:6 > + for (let table of tables) { Are we using `let` now??!? =D > Websites/webkit.org/wp-content/themes/webkit/scripts/global.js:22 > + if (backgroundImages.length == 0) NIT: you could use `!backgroundImages.length` instead
