Zoomed SVG image rendering comparison between Chrome and Safari

Hello, I'm working at miro.com where we build a whiteboard for real time collaboration of multiple users.
We faced a problem with rendering of the vector images with Canvas API in Safari. 
Here is the demo page: https://codesandbox.io/s/festive-roentgen-upjfvg?file=/src/index.js
You can see that the image is blurred in Safari but if you open it in Chrome you'll see that the image looks sharp.
The problem appears after the image is zoomed using the CanvasRenderingContext2D.setTransform() method. This affects many of our users on iOS and macOS devices.
Please tell us what can we do to eliminate this blur effect?
