Ambiguity Regarding Sending Keys to Option Elements

In chapter 12. Elements, section 12.4 Interaction:
In element send keys step 8 under the case labeled:

The user agent renders element as something other than a text input control (for example an input element in the color state being presented as a colorwheel):

I would like clarification on the expected behavior of sending keys to option elements. Strictly adhering to the spec, option elements would have their value themselves changed, and I wanted to confirm if this is intended behavior as it is somewhat strange. It appears that Firefox sends keys to the value of the parent select element rather than the options element, which perhaps is more reasonable and what was intended.

If Firefox's implementation is correct, would the same apply to options with datalist element parents that connect to input elements? Here is a stock example of the scenario I am referring to if it's confusing

Any confirmation or discussion would be appreciated.

Start with chapter 12, “Elements,” section 12.4, especially element send keys step 8 and its non-text-input case. Compare the specification wording with Firefox behavior for option elements under select and datalist, then clarify the intended handling in the specification, including whether the parent control receives the value.
