[Feature Request] debounce for dcc.Dropdown(multi=True) #3620
Description
When using the dcc.Dropdown with multi=True, each selection/unselection of an item trigger a change of the value prop.
It would be great to have a "debounce" feature implemented where the value is changed only when the dropdown is closed (or the x / deselect all shortcut is clicked) and the selection has changed.
