Steps to Reproduce

1. Create an app that declares a dialog and a web item as per the excerpt below.

4. Click on the "My webitem" menu item.

Descriptor excerpt:

"dialogs": [{
  "key": "my-dialog",
  "url": "/etc"
}],
"webitems": [{
  "key": "my-webitem",
  "name" {"value": "My webitem"},
  "location: "system.user/user-content",
  "target": {
    "type": "dialogmodule",
    "options": {
      "key": "my-dialog"
    }
  }
}]

Note that targeting dialog (rather than dialogmodule) also does not work.
