--- Comment #3 from Rui Chen <ruich at microsoft.com> ---
Sorry for the unclear description.
Double-tap-to-zoom on http://www.kappabashi.or.jp/en/ does work well on Safari.

UPDATED REPRO STEPS:
1. Load above static web page I wrote in Safari
2. Double tap the text to zoom-in
3. double-tap-zoom-out doesn't work now. But if remove the `click` event listener, it will work well.

I think there are some conflicts between `click` event listener and double-tap-to-zoom. --


HOW WE FOUND THIS:
In our app, we inject following codes into WKWebView to listen the click events.
After that, double-tap-to-zoom is broken on most of web pages.

http://www.kappabashi.or.jp/en/ is a sample which can't zoom in the text after the inject.
