Video JS embed issues across many browsers, debugging help needed.

Description

Previously, this video JS from SafeShare embed works without error, however, recently this caused many errors in browsers. I understand the script is used by SafeShare via FireBase. However, can anyone troubleshoot the exact issue or know the fix for this? Thanks in advance. The iframe embedding example:

<iframe allow="autoplay; fullscreen" src="https://safeshare.tv/vjs-embed/lgI16JfIXA0?autoplay=0&mute=0"></iframe>

In some browsers, screen automatically scrolls or jumps to middle or random portion where video is embedded (example: https://safeshare.tv ; the screen will jump to the middle after 10sec), in some browser, all video will always autoplay, some never autoplay, some are always muted (despite autoplay=0 or 1). All browsers display some kind of errors or buggy behaviour.

Reduced test case

https://safeshare.tv

Steps to reproduce

Embed the iframe as above.
Open any browser.
Some browsers automatically scroll to middle or end of page, some always autoplay, some never autoplay, some are always muted (despite autoplay=0 or 1)
DevTool shows numerous warning errors.
