Description

Videos in the <video> tag are not shown in web applications for bots. I need to display video for users of my web app, but it is not shown in web apps on iPhone. Telegram apps on Android, Windows and macOS don't have such problems, as well as Safari browser on iPhone when opening web app by url. My web app is react.js application, and I'm using a simple <video> HTML tag for displaying the video. Also, I'm using autoplay muted and playsinline attributes. I have tried it with simple HTML document with video tag. Tried .mp4 and .mov videos. Tried to make XMLHttpRequest to preload video and use blob URL. Don't know what about iPads.

Expected Behavior

Video must be visible in web app using telegram on Iphone.

Steps to Reproduce

1. Create web app with <video> tag and correct src in it.
