IOS 14.4.1 WebView HTML content CSS Position:fixed Disappear when scroll

I have an IOS app with a Web View. The website have a fixed header and footer. Since the update to 14.4.1 the header is pushed down, and the footer becomes invisible when the page is scrolled.

Correction: iOS 16.4.1.

Same here since the last IOS update. Created a simply html page with just a fixed header bar, empty line breaks, and nothing else. As you scroll down, the header bar also gets pushed down. Works perfect in Safari on IOS, just not the web view.

Same here CSS Position:fixed in a WKwebview with iOS 16.4.1.
