It's also in the 8.1 betas. You should file a radar.

Some stuff causes the entire webpage to reload or Safari to hang. For example, visit http://getemoji.com/ and start typing in the search box. You can't do it on an iOS 8.x device without the page reloading.

Notably, Chrome and Mercury work fine, so you could suggest that your users switch to third-party browsers based on UIWebView. (I didn't test out WKWebView.)
