Multiselect Combo Box: allow showing all labels

[OlliTietavainenVaadin]

Describe your motivation

Based on feedback: https://vaadin.com/forum/thread/18816965/p-vaadin-v23-2-0-includes-component-multi-select-combo-box-p For me, for example, the new Vaadin mscb is not usable, because it doesn't provide option to always show full item labels.

There should be an option to not collapse the tags even if it might look awkward with a lot of selected items.

Describe the solution you'd like

Every selected item should be visible and not collapsed.
