* ensure that the first option is always active
This will ensure that the first non-disabled option is the active one if
no other active options exist. This means that any time you search for
something that the first result is the active one and you can just press
<kbd>Enter</kbd> to activate the option.
However, there are a few rules that we have to take into account:
- If you just open the Combobox, and there is a `selected`
Combobox.Option, then we can't make the first option the active one.
The first selected Combobox.Option has precedence over this one. This
is important and rather tricky because Combobox.Option's register
themselves at some point (later) in time.
- If you already have an active option, then that option should stay
active. If it changes position, then the activeOptionIndex is adjusted
to account for that.
- If you "mouse leave" an option, then no option should be active. It
will be re-enabled the moment you start typing OR if you re-open the
Combobox. Otherwise, it can happen that you are at the bottom of the
list, mouse leave, and we scroll all the way back up to make the first
item the active one which is not good for UX reasons.
