Consecutive citations use a wrong CSL position definition

[brotz]

Description

I've been trying out Typst for some time and it's such a pleasure to with! There's only been one problem so far:

Description

I'm using a "note" citation style, where citations are put into footnotes. The style should render the word "ibid" when the same citation appears for the second (third, etc.) time in a row (there is some text inbetween those citations, but no other citation). This is achieved using the position property in the CSL file, like so:

<citation>
  <layout delimiter="; ">
    <choose>
      <if position="ibid-with-locator">
        <!-- Same citation as the one before, with a supplement, e.g. #cite(<key>, supplement: "something") -->
      </if>
      <else-if position="ibid">
        <!-- Same citation as the one before, without supplement -->
      </else-if>
      <!-- Other cases... -->

Take this example Typst source using such CSL style:

I've said it before.@mykey

And I'll say it again.@mykey

Life moves fast.#cite(<mykey>, supplement: "p. 42")

This results in three footnotes, the first one containing the citation, the second one being incorrectly empty, and the third one correctly containing "ibid., p.42" as per my style.

When not specifying a supplement in the second citation, I would expect the position="ibid" to be used. Instead, position="ibid-with-locator" is used, but since the locator variable, where Typst normally puts the supplement, is not defined, the evaluation fails. Nothing gets printed out, and my footnote where the text "ibid" should be is instead empty.

Workaround

I have made a simple workaround by modifying my CSL file the following way:

<citation>
  <layout delimiter="; ">
    <choose>
      <if position="ibid-with-locator">
        <choose>
          <if variable="locator" match="any">
            <!-- Put the original contents of <if position="ibid-with-locator"> here.  -->
          </if>
          <else>
            <!-- Put the contents of <if position="ibid"> here.  -->
          </else>
        </choose>
      </if>
      <else-if position="ibid">
        <!-- This won't be used by Typst -->
      </else-if>
      <!-- Other cases... -->
