Government of canada form: https://www.canada.ca/content/dam/cra-arc/formspubs/pbg/t2200/t2200-fill-24e.pdf

Behaviour: If you check boxes in this form, in any browser, the checked boxes, in Acrobat Reader, go from Yes to unchecked and No to Yes.

In the example below, in Firefox, I checked Yes for #1 and No for #2. I then saved the form.
When you open the document in Adobe Reader and Enable All features, the Yes will no longer be checked, and the No in #2 will migrate to a yes.

Expected Behaviour: the checked value of a checkbox from a browser should not change when opened in Adobe Reader.
