Description
Steps to reproduce
When I upload webm video it's showing like video for me. But when I repost it to any user — they see it like .webm file (document). Also when I restart Telegram — I start seeing it like .webm file too. Even if I don't delete that .webm from my computer.
- Upload webm video to your saved messages
- It's showing like video
- Repost it to any user
- Users will see it like file
- Restart Telegram
- You too will see it like file

Research direction
The report names no source files, tests, or entry points. First reproduce the behavior in Telegram Desktop 4.3.1 on Windows 10 using the linked WebM: upload it to Saved Messages, repost it, and restart the client; done means the video remains recognized as a video after reposting and restart.
