The Calcite autocomplete component currently shows all autocomplete items whenever the component has focus and bolds text in each of the autocomplete items that matches the user's input (case-insensitive). When there are many options, sometimes the bolded items are not in view as the user types, giving the impression that there are no matches. The proposed change is to alter the behavior of the component to align with that of the ArcGIS JavaScript SDK's search widget, which only displays the items (suggestions) that have matched text, and even then, only a few (six by default, but it is customizable). I think the autocomplete behavior should either be changed to the proposed behavior, or there should be a Boolean property, like "filter-results", which would apply the proposed behavior if set to true.
