QtSvg ignores clipping on SVG paths

When rendering .svg images in KDE Gwenview, clipping of paths seems to be ignored. I.e. paths that should be cut off are not, but are instead drawn on top of / below other paths.

Attached test.svg as well as a screenshot of side-by-side rendering by gwenview (wrong) and chromium (correct).

Reproducible: Always

Steps to Reproduce:
1. Load test.svg
2. Observe unclipped paths

Actual Results: Paths are not clipped.

Expected Results: Paths should be clipped.
