When an alt group contains a return element, it seems like the bounding participants are not ordered correctly

This MRE shows how the alt group seems flipped:

#import "@preview/chronos:0.2.0": diagram, _seq, _ret, _alt, _col, _par

#set page(width: auto, height: auto, margin: 1cm)

= Expected result

#diagram({
  _par("A")
  _par("B")
  _col("A", "B", width: 3cm)
  _seq("A", "B", enable-dst: true)
  _alt([desc], {
    _seq("B", "A", disable-src: true, dashed: true)
  })
})

#pagebreak()

= Actual result

#diagram({
  _par("A")
  _par("B")
  _col("A", "B", width: 3cm)
  _seq("A", "B", enable-dst: true)
  _alt([desc], {
    _ret()
  })
})
