iOS 14+ `<Image />` only showing first frame of WebP animations

[btroia]

Please provide all the information requested. Issues that do not follow this format are likely to stall.

Description

The latest RN documentation indicates full support for WebP images on iOS "out of the box" - however, it only appears to load static WebP's - animated WebP's do not play (only first frame is shown).

React Native version:

0.63 (Expo), 0.64 (native)

Steps To Reproduce

1. On iOS 14+, create an <Image /> that loads animated WebP image uri, i.e.: https://storage.googleapis.com/downloads.webmproject.org/webp/images/dancing_banana2.lossless.webp
2. Only the first frame is shown (no animation plays - see snack below)
3. Note that the animation does play when viewed in Safari (outside of RN)

Expected Results

Animated WebP should play.

Working example showing the issue:

(choose the iOS preview tab to view - notice only a static WebP image loads)

Should also update documentation at https://github.com/facebook/react-native-website/pull/2418 to clarify that WebP is not yet "fully" supported on iOS
