Circle anchors detached from the circle elements. Can anyone provide an explanation and a solution to this problem? This problem keeps cropping up, it really bothers me.

#set page(paper:"a4", flipped:true, margin:1cm)
#set align(center + horizon)
#set text(size:1em)

content((rel:(0,0,0.3), to:"z.end"), $z$)

let cir-num=1
for i in range(cir-num) {
let interval= 2* pi/cir-num
rotate(z:interval* 1rad)
on-yz(x:0, {
circle((0,4), radius:2, name:"cir") ;
line("cir.center", "cir.20%")

}) } 

})

})

Fixed with #1063.
