Description

The client uploads all >10 MB videos with bogus documentAttributeVideo w, h parameters of 848x484 (484x848 if vertical). This causes video playback issues on other clients relying on the video attributes.

Steps to Reproduce

1. Upload literally any 1080p video >10 MB with the highest quality setting selected
2. Video is correctly uploaded as a 1080p video, but the width, height attributes are always 848x484
