Android Chrome can't zoom at all (anywhere on site, or on chart).

You can if you turn on the "desktop site" option (in the menu in the top right). I believe this works for all sites.

You can force enable zoom on all pages in accessibility settings

I cannot on same (iPhone SE)

I have an iPhone SE with Safari, and it works.

My goodness, you're right, I was using Chrome blush

Zooming is working for me in iOS Safari as well.

It, interestingly, is browser specific. Safari can zoom, chrome can't.

I've been annoyed by chrome's zoom behavior, so this is a delightful find. Thanks!

Safari ignores directives by the website to disable zoom.

Lots of site owners disable zoom because they think they know best when it comes to content-size. Disabling zoom also makes the site slightly more responsive because when a touch occurs, the browser doesn't have to wait a few hundred milliseconds to see if a 2nd finger is going to be touched to start a zoom action.

Yep, as of iOS 10 https://webkit.org/blog/7367/new-interaction-behaviors-in-io...

And thank god for that, there were so many sites that disabled zoom for seemingly no reason, and somehow it was always the ones with tiny text or images.

Same here on Sailfish XA2 with Firefox running on Android emulation so I don't know WTF the OP is using ;-)

Same here with same OS version.
