Handling multiple form definitions (ui:annotationForm)

It is possible for a single class to be assigned multiple forms with
ui:creationForm or ui:annotationForm

A permanent solution probably requires either a mechanism to give the user a choice, to hardcode an order of preference (e.g. based on the document ui:annotationForm is defined in) or allow a user to specify a priority level for the form.

For my immediate purposes I have the problem that the same ui:annotationForm statement can be specified in multiple documents, which results in the form being rendered multiple times.

The logic to return the form to be used is in:
https://github.com/solid/solid-ui/blob/766c3f7906f991c582baad50f29061c1c9836a55/src/widgets/forms.js#L992

My temporary solution is to remove duplicate forms (i.e. ignore which document the ui:annotationForm statement was defined in). The two lines of code are here:
https://github.com/josephguillaume/my-solidos-patches/blob/afad1a9cc443fc1c996eec5dcc9463f55c670a1f/solid-ui.diff#L46

Comienza con la lógica de selección de formularios en src/widgets/forms.js alrededor de la línea 992 y compárala con el parche temporal enlazado en solid-ui.diff. Determina cómo se representan las declaraciones ui:annotationForm repetidas de varios documentos y define el manejo previsto de múltiples formularios; done debería impedir que se renderice repetidamente el mismo formulario, teniendo en cuenta el comportamiento de selección aún no resuelto.
