it seems that selecting multiple items from a filterable MultiSelect can be quite a pain if you want to select items that are filtered. I have adapted the snippet from your documentation to show the problem I'm currently facing with a user request: https://blazorrepl.telerik.com/cRaRPKvP25KEN0xs54 by making the dropdown not close automatically and be Contains filterable.
If the user wants to select all items containing the number 3 from the list it might go something like this: User types 3 into the input box. Multiselect shows items containing 3. User selects an item from the filtered options. Multiselect adds the chosen item to the list of selected items and clears the filter. User now has to type 3 again to filter the multiselect again etc.
So the "clear the filter after user selects item" is the problem here. Is there any way to avoid this, or select multiple items in "one go" from the list of filtered items?
