SwiftUI: How to size a popover to content with a Form on iOS 14.5

I am having a problem getting a popover on an iOS app (simulator iOS 14.5) to size correctly to the content if I use a Form in the popover.

I have a popover as such:

Code Block 
...
.popover(isPresented: $showPersonEditor) {
   PersonEditor(chosenPerson: $chosenPerson)
      .environmentObject(document)
}
...

Within my PersonEditor struct, if I create a Stack in the body as follows, then the popover sizes correctly according to the content:

Code Block 
...
VStack(spacing: 0) {
   Text("Person Editor").font(.headline).padding()
   Divider()
   TextField("Name", text: $name, onEditingChanged: { began in
      if (!began) {
         document.renamePerson(chosenPerson, to: name)
      }
   }).padding()
   TextField("Add info", text: $infoToAdd, onEditingChanged: { began in
      if (!began) {
         chosenPerson = document.addInfo(infoToAdd, toPerson: chosenPerson)
         infoToAdd = ""
      }
   }).padding()
   Text("Test")
   Spacer()
}

However, when I use a Form within the VStack in order to group my fields, then the popover doesn't size correctly anymore! Instead it just shows the popover title and a tiny bit underneath.
This is the code with the form:

Code Block 
VStack(spacing: 0) {
   Text("Person Editor").font(.headline).padding()
   Divider()
   Form() {
      Section {
         TextField("Name", text: $name, onEditingChanged: { began in
            if (!began) {
               document.renamePerson(chosenPerson, to: name)
            }
         }).padding()
         TextField("Add info", text: $infoToAdd, onEditingChanged: { began in
            if (!began) {
               chosenPerson = document.addInfo(infoToAdd, toPerson: chosenPerson)
               infoToAdd = ""
            }
         }).padding()
      }
      Section(header: Text("Test")) {
         Text("Test")
      }
   }
   Spacer()
}

This worked with the simulator for iOS 13.4.x but does not work with 14.5.
Can anyone help?
Thanks,
Kristian.
