Falco landed this yesterday, which should hopefully resolve the issue:

FIX: Skip composer media optimization on EOL iOS versions (#42055)

committed 02:54PM - 27 Jul 26 UTC

Previously, the WASM-based composer image optimization crashed the page on devic…es stuck on EOL iOS versions (e.g. iPhone 8 / iPad 5 on iOS 16.7), where WebKit's memory watchdog reloads the page instead of raising a catchable error. This change detects the iOS major version from the user agent (falling back to Safari's `Version/` token on iPadOS, whose desktop UA masquerades as macOS) and skips client-side optimization entirely on iOS 18 and older, matching the EOL list at https://endoflife.date/iphone. Affected devices upload their original files instead.
