Group Checkbox Deselect Very Slow

[David]

Hi

The MultiSelect component is very slow when using the group header checkbox to deselect a list of items. You can see each item getting deselected one by one but it is very slow especially when the list of items is quite large. The user has to wait until each item has been deselected before continuing with their search/selection.

The same component in the ASP.Net Core is very fast and is how I expected the Blazor version to behave. 

Is there anyway to increase the performance of the group checkbox deselect?

See attached video to see what I mean.
