Transforms appear to have no effect on clipping

[J-Cake]

I seem to have run into an issue where the transform I set (translation only at this point) has no effect on clips.

Take the example below

ctx.clear(SolidSource::from_unpremultiplied_argb(0xff, 0xff, 0xff, 0xff));

ctx.set_transform(&Transform::translation(50., 50.));
ctx.push_clip_rect(IntRect {
    min: IntPoint::zero(),
    max: IntPoint::new(100, 100)
});
let fill = Source::Solid(SolidSource::from_unpremultiplied_argb(0xff, 0xff, 0, 0));
ctx.fill_rect(0., 0., 200., 200., &fill, &DrawOptions::default());

The result I get is the following:

If the transform were working, it would begin at (50, 50) and extend to (150, 150), however, reaches from (0, 0) to (100, 100). You can tell because the red rectangle is only 50x50 and offset to (50, 50).

If this is expected, what would the best approach be for computing the absolute transform, such that I can offset the clip accordingly?

This can also be confirmed by applying an incremental rotation to the transform, and observing where the clipping occurs.
