Reproduction of unstable work of dynamic viewport units in different browsers on IOS (maybe there is also android browsers, but I failed to reproduce the behvaiour) 

Browsers that misreport `svh`, `lvh` units

 - Brave (iOS)

 - Arc (iOS)

 - Opera (iOS)

 - [Telegram Webview (iOS)](https://github.com/TelegramMessenger/Telegram-iOS/issues/1551)

This behaviour causes cumulative layout shift when `min-height: 100lvh` used
