interactive annotation about <TextArea> with perRegion="true"

[Michel-liu]

Hi~ Thanks for this wonderful project. Currently, I try to perform interactive annotation for automatically polishing the description of each bbox region via a LLM, which looks like

<Image name="image" value="$image">
<RectangleLabels name="bbox" toName="image">
<Label value="car" />
<Label value="cat" />
</RectangleLabels>
<TextArea name="description" toName="image" perRegion="true" maxSubmissions="1" editable="true" required="true"/>

However, when I submit the text, I am unable to transmit the annotated description to the predict function in the label-studio-ml backend. It seems perRegion="true" disables this process. How could I address this issue? Thanks.
