Make autocomplete mentions dropdown scrollable

[alfazaz]

Hello !

When we type a mention in composer, an autocomplete dropdown is showing but it is limited to 10 items. It can be tricky when many mentions are beginning with same chars. For example, on my forum, if I begin to type @Promo, it gives this :

and it's not possible to see Promo 19-20 group mention for example (because it is after the 10 items showed).

Is it possible to make the dropdown scrollable with all items found ?
