Custom Attachment view definition not being used when present

Describe the bug
Likely related to or a manifestation of both #3988 and #3328.

To Reproduce
Steps to reproduce the behavior:

1. Define a custom Attachment view definition

<viewdef name="Attachment (2)" class="edu.ku.brc.specify.datamodel.Attachment" type="form" gettable="edu.ku.brc.af.ui.forms.DataGetterForObj" settable="edu.ku.brc.af.ui.forms.DataSetterForObj">
	<desc>The Attachment Table</desc>
	<enableRules/>
	<columnDef>p,2px,p:g</columnDef>
	<rowDef auto="true" cell="p" sep="2px"/>
	<rows>
		<row/>
	</rows>
	<rows>
		<row>
			<cell type="label" labelfor="origFilename" label="FILENAME"/>
			<cell type="field" id="origFilename" name="attachment.origFilename" initialize="editoncreate=true" uitype="browse" isrequired="true"/>
		</row>
		<row>
			<cell type="label" labelfor="title" label="TITLE"/>
			<cell type="field" id="title" name="attachment.title" uitype="text"/>
		</row>
		<row>
			<cell type="label" labelfor="ispub" label=""/>
			<cell type="field" id="ispub" name="attachment.isPublic" uitype="checkbox" label="Make Public"/>
		</row>
		<!--   <row><cell type="subview" id="metadata" name="attachment.metadata" viewname="AttachmentMetadata" colspan="3"/></row> -->
	</rows>
</viewdef>

2. Upload a Collection Object Attachment
3. See that the custom form is not being used (UX testers can verify by going to the meta menu '-> Form Definition' and see that there is no 'Edit Form Definition' button visible). Also notice the Title field is still required.

Expected behavior
Custom attachment forms should be used when they exist.

Reported by Szuzsanna @ NHMD, via email (ento collection)

Since we upgraded to v. 7.9.6.1, we’ve noticed that the user interface of attachment metadata has been working oddly.
Before vs After save:

This change is not expected or desired for the attachments. I would be glad if you can look into it.

workaround:

I replaced the Object Attachment view definition with a port to the "Attachment" form, which is defined exactly as the CO Attachment form except without dot notation or the ordinal field. I opted to add the Attachment view and definition as the endpoint for the Object Attachment form because it can be accessed in the visual XML editor and schema config.
