Neither does Safari on macOS – which honestly seems like the correct behavior, given that this will inevitably be used by websites in user-hostile ways.

Safari only shows HDR in videos, not photos. It's possible to just show a single-frame video though.
And I could see Safari changing its behavior to only allow HDR for actually playing videos (or even playing videos with actually varying content, if websites start playing clever games with one second loops of still images), or maybe only after confirming an "I am wearing sunglasses right now" prompt.
If it were to become a real problem I'd sooner see Apple, of all vendors, leave it as one of the many settings flags in Safari than intentionally avoid or remove support for wide range media in their app.
Related: there is also a CSS property coming which allows sites to control which page content should be clamped to standard range or not. Worst case you can just add an * !important override in your Safari->Preferences->Advanced->Style Sheet if nobody else considers it problematic but you still wanted to clamp things (in Safari, otherwise you can just disable HDR).

It looks like the current Safari developer preview supports it for images, according to the Mozilla bug.
