Automatic resumption of AudioContext doesn't work well on Safari

I apologize for the lack of details, I don't own any Apple devices personally.

A user observed sound not playing back in Safari. It failed both on https://archive.org/details/win3_MidMM211 and on my project, which uses autoResumeAudioContext alongside custom Web Audio code.

When I added buttons to my project instead of telling people to click on an empty page, it started working. I did not explicitly add a resume to the buttons.

So I'm guessing that autoResumeAudioContext on Safari works for buttons but not other elements like canvases.
