rotate(270) does not adjust with and height for viewport and image when rendering

[ase379]

When I use the image attached, it looks fine in the web. But on a Canvas, the image is not rotates

Web:

Image

I debugged it an it seems, as if the viewport is not rotated. The same for the width and the height.
I now intercepted the width and height, but its quity hacky. I did not find a solution for the viewport now.
Can you fix this ?

Yep, this SVG feature is currently unsupported. Sorry.
