RTE inside multifield is not showing up in authoring dialog box

Hi,

I'm working on AEM cloud project (6.5) and facing 2 issues with coral 3 multifield.

1)RTE in side coral-3 multifield (granite/ui/components/coral/foundation/form/multifield) it is not appearing in authoring dialog box.

2)Drag and drop functionality for image is also not working inside multifield.

Note:- I tried using coral-3 fileupload resourceType (granite/ui/components/coral/foundation/form/fileupload) for image fields but still drag and drop functionality was not working.

Can someone help me with this issue? why it is not working?

Below is my cq:dialog.
