// "google.com ".
// (4) was_toggled_into_keyword_mode == true, has_temporary_text_ == true
// The user had just typed tab to enter keyword mode, e.g.
// "google.com<tab>".
//
// For states 1-3, we can safely handle the exit from keyword mode by using
// OnBefore/AfterPossibleChange() to do a complete state update of all
// objects. However, with state 4, if we do this, and if the user had tabbed
// into keyword mode on a line in the middle of the dropdown instead of the
// first line, then the state update will rerun autocompletion and reset the
// whole dropdown, and end up with the first line selected instead, instead of
// just "undoing" the keyword mode entry on the non-first line. So in this
// case we simply reset |is_keyword_hint_| to true and update the window text.
//
// You might wonder why we don't simply do this in all cases. In states 1-2,
// getting out of keyword mode likely shouldn't put us in keyword hint mode;
// if the user typed "google.com f" and then put the cursor before 'f' and hit
// backspace, the resulting text would be "google.comf", which is unlikely to
// be a keyword. Unconditionally putting things back in keyword hint mode is
// going to lead to internally inconsistent state, and possible future
// crashes. State 3 is more subtle; here we need to do the full state update
// because before entering keyword mode to begin with, we will have re-run
// autocomplete in ways that can produce surprising results if we just switch
// back out of keyword mode. For example, if a user has a keyword named "x",
// an inline-autocompletable history site "xyz.com", and a lower-ranked
// inline-autocompletable search "x y", then typing "x" will inline-
// autocomplete to "xyz.com", hitting space will toggle into keyword mode, but
// then hitting backspace could wind up with the default match as the "x y"
// search, which feels bizarre.
