Edge saves form field values that I did not enter

   I use a web site with a feature that opens a its own search page with many values filled in with data copied from a record on the site.  This action does not add any of the pre-filled values to autofill.  This is good.  Now, if I change, delete, or add a value to any field and resubmit the search, Edge doesn't just save the value I typed as autofill, it saves everything including specifically the values provided by the web site which I never touched.  The result is that I end up with thousands of useless values being saved as autofill data.  They not only obscure access to the values I did enter myself but they roam and get pushed to all my devices.

   Edge should only save autofill values that the user enters whether via typing or pasting or other input method but not values supplied by the web site itself whether by HTML or script.
