Chart is stretching vertically and horizontally without maintaining aspect ratio of elements on Pinch

[ratz6]

When I use Pinch in my Chart JS treemap, my Elements in treemap start to expand horizontally and vertically.

It should expand like how pan and wheel expands on web keeping the elements aspect ratio in sync.

RIght now it works like this on mweb > https://jsfiddle.net/sohrabi2050/em406Lvt/3/

Check this out on mobile , which is what I expect in pinch >

It is linked to this issue I believe : #792

How do we achieve this ? @kurkle
