Embedding posts and scrolling on their own

[osapon]

Expected behaviour

I don't want they to scroll.

Actual behaviour

I embed a video post with audio, it seems to automatically scroll to the embedding location when the page is viewed.
Doesn't happen with images or videos that have no sound.

Steps to reproduce the problem

These are no problem.

This issue seems to be caused by calling the HTMLElement.focus() method inside React by setting the autoFocus attribute of the play button implemented in the video player to true.

mastodon/app/javascript/mastodon/features/video/index.js

Line 620 in e0bdaea

<button type='button' title={intl.formatMessage(paused ? messages.play : messages.pause)} aria-label={intl.formatMessage(paused ? messages.play : messages.pause)} className='player-button' onClick={this.togglePlay} autoFocus={detailed}><Icon id={paused ? 'play' : 'pause'} fixedWidth /></button>

Also, for posts embedded in other websites, I think you need not to focus on the play button.
Therefore, I think it is necessary to process to determine whether the post is embedded.

This problem remains in Mastodon 4.0.0.

I built my own Mastodon server.

Then I deleted autoFocus and run server, the problem has been resolved and no other differences in behavior from the original can be found.

@ClearlyClaire added autoFocus in #12498.

I seem to this attribute inserts when a status embedded but causes this problem.
So I think autoFocus don't need in embedded status.

How about ?
