Safari Extension Breaks Auto-Play Blocking

Nobody has claimed this yet.

### Steps To Reproduce

If the Bitwarden extension is enabled some embedded videos will play, even if Safari's preferences are set to block auto-play. Autofill doesn't have to be turned on; the extension simply being enabled and reading the page is enough to break Safari in this case.

Add Bitwarden extension. Set Safari Preferences, in Preferences, Websites, Auto-Play to Never Auto-Play or Stop Media With Sound. Go to
https://gbtimes.com
(just one of the ones I've come across, but it makes a good example).

### Expected Result

Video no play.

### Actual Result

Video play.

### Issue Tracking Info

- [x] I understand that work is tracked outside of Github. A PR will be linked to this issue should one be opened to address it, but Bitwarden doesn't use fields like "assigned", "milestone", or "project" to track progress.

Reproduce the issue in Safari 18.3 on macOS with Bitwarden version 2025.2.0 enabled and autoplay set to Never Auto-Play or Stop Media With Sound, using gbtimes.com as the example. Trace the Safari extension's page-reading behavior to identify why merely enabling it permits embedded videos to play, then verify that autoplay blocking remains effective without autofill enabled.
