MultiSelect: Uncaught ReferenceError: filter is not defined

Describe the bug

When we open the MultiSelect and press Tab key there is an error in console Uncaught ReferenceError: filter is not defined.
It comes from the https://github.com/primefaces/primereact/blob/prod/components/lib/multiselect/MultiSelect.js line 280 hide(filter)
Filter variable is undefined and also hide function doesn't take any parameters (line 534)
It casues the issue that MultiSelect dropdown is not closed after tabbing to the next form element from it.
After removing locally filter parameter from the line 280, everything works fine.
