Artifact on the edge of canvas

[dimi-colossal]

Hi folks,

We've noticed an issue. When the rive element edges are visible to the parent element, we get some line artifacts. It was the same on top/bottom and left/right (depending on how we scaled it).

Here's a video of the issue: https://github.com/user-attachments/assets/c298a766-3b52-4740-a878-f7af147e36cb
