I have placed at the end of the element with overflow: auto CSS. Then suggestions were expanded into scroll area (therefore not visible on the tap/write) and were overflowing the parent element instead.
Currently I have no idea how to make them visible. I tried to set --paper-listbox: { position: fixed; width: initial; } but the width is still broken and it is not 100% working solution anyway.
Anybody any suggestions on this?
