Steps to reproduce the problem:
1. I filed this bug countless times and they keep getting maliciously closed as wontfix because a dev doesn't like me. I''ve provided sufficient reason to get this fixed along with many many many many other users complaining about it and I keep getting ignored. I'm begging for some help here.

Navigate to youtube.com, and open a video in a new tab. Note the video does not autoplay until you click the new tab you've opened.

What is the expected behavior?
With an effective flag, or a workaround, for media to autoplay when opened in a new tab without gesture input.

What went wrong?
Till 60.0.3082.0 we have gesture-requirement-for-media-playback flag and on disabling it we used to have audio playback on background tabs as well. From 60.0.3083.0 flag is not seen and autoplay policy flag is seen and on enabling/disabling it unable to listen any audio playback on background tab until you navigate to that tab.

Did this work before? Yes 60.0.3082.0

1. I used to be able to middle click or right click videos and open them in new tabs, and when they launched they would autoplay without any user interaction required. This included clicking the tab or whatnot. This was imperative to an efficient workflow with the work I do at my job.

2. This behavior was changed. Videos would no longer autoplay when opened in a new tab. I did some googling and found out a chrome flag was added so that I could still have videos autoplay. I found this out because I found multiple forum posts with many users complaining about this new no-autoplay behavior, and this was what everyone had suggested. Because I had a workaround, I was happy and decided not to open an issue about it on chromium bug tracker.

3. The old autoplay flag was replaced with the current one. I noticed I had to interact with the youtube tabs for them to autoplay. I found what the new flag was called and tried using it but it was ineffective. I searched again on google and found many forum posts again complaining about the new behavior, but I saw these issues being closed as wontfix and no workaround or alternative solution was shared or provided other than to use another browser.

I don't see what the major block is to simply make people happy again. Even if it's a setting buried deep or obscurely named, users who want this behavior should have the option to enable it especially since it was there before and many many users keep asking for it back and none of you developers who keep closing the issue have provided us with any alternative, workaround, or solution.
