html fabric.js svg canvas JavaScript

I've been working on this all day and I'm having trouble rendering SVG images on an HTML5 canvas using Fabric.js. I noticed that when I zoom in on my canvas, some SVG elements disappear completely. This is particularly problematic because I'm trying to create a dynamic editing interface where users can resize and manipulate these elements. I've set up a basic Fabric.js instance and added an SVG object, but upon zooming in, certain paths seem to render incorrectly or not at all. Here's a simplified version of my code: ```javascript const canvas = new fabric.Canvas('c'); fabric.loadSVGFromURL('path/to/your/image.svg', function(objects, options) { const obj = fabric.util.groupSVGElements(objects, options); canvas.add(obj); canvas.renderAll(); }); canvas.setZoom(2); ``` When I set the zoom level to 2, some of the elements in the SVG disappear or only partially render. I've checked the SVG file for any potential errors, and it looks fine to me. Additionally, I made sure that the paths are properly closed, as I read that improperly closed paths can sometimes lead to rendering issues. I've tried adjusting the `canvas.setZoom()` level and resizing the canvas element itself but to no avail. I also looked into the `viewportTransform` property to see if adjusting that would help, but I'm not sure how to implement that properly. Is there a specific approach or setting in Fabric.js that I might be missing to ensure that SVG elements render correctly at different zoom levels? Any insights or suggestions would be greatly appreciated! What's the best practice here? My development environment is macOS. Thanks in advance! Any pointers in the right direction?
