If TracFormsPlugin is used to embed a form within a ticket, the embedded form will have a Submit button, and so will the ticket.
A user might enter data in BOTH the embedded form and in the ticket fields. If the user then selects the ticket's Submit button, changes to the form will be lost. Users must be trained to always submit the embedded form first.
It would be desirable for the ticket Submit button to also trigger the embedded form's Submit button.
(Bonus points for only triggering the embedded form if new or changed data is present, but this strikes me as a much more challenging task.)
