Issue, when zooming with 2 fingers - Ipad-Safari

In chrome we added a meta tag :

which allows users to stay on diagram (canvas) when 2 finger zoom .

But in safari (ipad) above is not working, browser zoom happening.

The standard behavior is that if you start the pinch zoom within the Diagram, it’s OK if the fingers extend beyond the Diagram – it keeps zooming the Diagram.scale and not the whole page.

I just tried it now on an iPad to confirm that behavior.

You never did say what meta tag you are using, nor what it has to do with Chrome.

Meta tag is :<meta name="viewport" content="width=device-width, initial-scale=1.0, maximum-scale=1, user-scalable=no">

and in chrome its working as espected in chrome

Could you please be more specific about what your expectations are? Please describe in more detail how to reproduce the results that you are seeing. Please specify exactly how you want the behavior to be different. Also state which browsers you are using on which operating systems and on which devices.
