Fields editor and tc-popup-keep

Can someone confirm that the fields editor when re-consumed inside a popup fails to honour tc-popup-keep?

Here’s what I’ve tried…

<$tiddler tiddler=<<active-section-view>>>
<$eventcatcher selector=".fields-editor input, .fields-editor button" $click=<<noop>> $focusin=<<noop>> stopPropagation="always" tag=div>
<div class="fields-editor" style="width:700px">
<$vars newFieldNameTiddler="$:/temp/bk/newFieldName"
      newFieldValueTiddler="$:/temp/bk/newFieldValue"
>
{{||$:/core/ui/EditTemplate/type}}
{{||$:/core/ui/EditTemplate/fields}}
</$vars>
</div></$eventcatcher>
</$tiddler>

Note: the stopPropagation=always does not affect the issue.

Then I went the “simple” route…

<$fieldmangler $tiddler=<<active-section-view>>>
  <$tiddler tiddler=<<active-section-view>>>
    <$transclude $tiddler="$:/core/ui/EditTemplate/fields" mode="block"/>
  </$tiddler>
</$fieldmangler>

Understand, there are tabs in the popup. Many of them contain form elements (inputs, checkboxes etc) and none of them close the popup when they are used. The issue lies in the $:/core/ui/EditTemplate/fields input elements – something is somehow closing the popup the moment an input is clicked.

Thanks.
