Checkbox not showing in listheader when checkmark and multiple are true

I'm attempting to add a checkbox to the header of a listbox. From the documentation I've seen, the below code should do just that. It does put a checkbox with each item, bit it does not put a checkbox in the listheader. We are running zk 6.5.8.1.

<listbox 
model="@load(vm.incidentReport.irImages)"
emptyMessage="No Image Data" 
checkmark="true" 
multiple="true" 
id="picturesListBox"
selectedItems="@bind(vm.selectedImages)">
<listhead>
<listheader label="You are using ZK version: ${desktop.webApp.version}" />
<listheader label="Description"          />
<listheader label="Type"                 />
<listheader label="Date Added/Updated"   />
<listheader />
</listhead>
<template name="model">
<listitem hflex="1" height="150px">
    <listcell label="@load(each.title)" />
    <listcell label="@load(each.description)" />
    <listcell label="@load(each.type)" />
    <listcell label="@load(each.createdTs) @converter('dateTimeFormatConverter')" />
    <listcell vflex="max" height="150px" zclass="blah">
    <image src="@load(vm.getImageSrc(each))" style="max-height:100px;" />
    </listcell>
</listitem>
</template>
</listbox>

I've grabbed the fiddle from here: zkfiddle.org/sample/1q5ffui/1-Select-multiple-items-in-listbox-with-model

and modified it for checkmark=true (which worked as expected) and then imported it into our environment and the checkmark in the listheader disappeared.

The checkmark is not visible when I inspect the elements on the page, so it's not just there, but hidden.

I expect that we've got something set up in our environment that disables/removes that checkbox, but I have had no luck finding the offending css/code/whatever. Anyone have any thoughts?
