Suggestions on form elements can’t be accessed by script on the page.
They only expose information that the user selects.

(What does “limited” mean?)
If script can programmaticaly get at the spell check results, then it
exposes whether particular words are in the user’s dictionary to that
The assertion is that it is a violation of the user’s privacy for a web
page to know whether a word is in the user’s dictionary or not. An API
to perform spelling checks and return their results would expose this
information. As currently handled, spelling checks are done purely at
the UI level, and information about the dictionary is not exposed to
