Invalid bounding box

[Robotechnic]

Hello,

I have the following code:

#import "@preview/cetz:0.3.4": *

#canvas({
    import draw:*
    content((0,0), "A", name: "A", anchor: "west")
    line("A.east", (rel: (angle: 25deg, radius: 1)), name: "A-B")
    let branch = {
        content("A-B.end", "B", name: "B", anchor: "west")
        line("B.east", (rel: (angle: 0deg, radius: 1)), name: "B-C")
        content("B-C.end", "C", name: "C", anchor: "west")
        line("C.east", (rel: (angle: 0deg, radius: 1)), name: "C-D")
        content("C-D.end", "D", name: "D", anchor: "west")
    }
    get-ctx(ctx => {
        let bounds = process.many(ctx, branch).bounds
        rect(bounds.low, bounds.high, stroke: red)
        branch
    })
})

But the bounding box is not right:

If I add a set-transform(none), the bounding box is correct, but all the anchors are messed up, and that's not what I want. Any solution would be helpful as I need this to correctly place elements.

You have to reverse the current transformation, as process.many returns “final” canvas coordinates:

--- 8< ---
rect(..util.revert-transform(ctx.transform, bounds.low, bounds.high), stroke: red)
--- >8 ---

It works thank you!
