Tauri is not as platform-agnostic as Electron is because it uses different web views depending on the platform. I ran into a few SVG-related problems myself when trying it out for a bit.

For example, on Linux, it uses WebKitGTK as the browser engine, which doesn't render the same way Chrome does (which is the web view used on Windows), so multi-platform support is not totally seamless.

Using something like Servo as a lightweight, platform-independent web view seems like the way forward, but it's not ready yet.
