Multi-select search by typing breaks list after selection

[mdesco-crgl]

Version: 1.1.0

When using a multi-select, after a selection has been made, using the "type to search" feature returns no results and breaks the list.

Because selections populate the input field, the icontains search searches against this entire input, returning no results. Even if the user were to clear their selections (using backspace or the "none" button), the list of options remains empty, as now it is searching against the empty string. The only way to display the tickboxes with a full list of options is to reload the page. This is critically detrimental to the UX for long lists or when an option must be selected in the middle of an unsaved form.

This is observable from the live demo documentation

A colleague informed me that the type search does work after making selections if the input text is fully cleared.

There is a usability concern remaining where

1. if the user uses the "None" button, the dropdown list still only includes the previous typed results
2. if a user clears or removes text in the input (e.g. deleting Atari 2600), the selection remains checked.
