Visiting https://help.rive.app/runtimes/overview/web-js with Firefox 124.0.1 shows errors in the sample:

Uncaught TypeError: CanvasRenderingContext2D.clip: Argument 1 does not implement interface Path2D.

Provide a Repro

Visit https://help.rive.app/runtimes/overview/web-js with Firefox and look at the animation.

Expected behavior

For it to work, same as Chrome.

Screenshots

Browser & Versions (please complete the following information)

• Browser: Firefox 124.0.1
• OS: Windows 11
• NPM Version: not my project

Reproduce the failure by opening the web-js overview sample at help.rive.app/runtimes/overview/web-js in Firefox 124.0.1 and compare it with Chrome. Start with the reported CanvasRenderingContext2D.clip error and the rive.js stack entries, then identify the relevant runtime or sample source. Done means the animation works in Firefox without the Path2D error, as it does in Chrome.
