PDF export as PDF form of a document that contains form controls does not embed the fonts used in the form controls for user input.
Since these fonts will be needed when filling in the form, it seems to me that they should be embedded but not subsetted, since one doesn't know what the user will type in the PDF form.
Steps to Reproduce:
Create a document with form controls
Export as PDF, check the "Create PDF form" checkbox, with "submit format" to PDF.
Fonts used in the form input fields are not embedded.
Fonts used in the form input fields should be embedded.

"LiberationSerif", used in the document text is embedded and subsetted. But "Carlito", used for the text box (user input in the PDF form) is not embedded.
