I have example directly from Material Angular for autocomplete chip. Once I add a chip, it does not loose the focus because you cannot click on it again unless you click somewhere else.
Here is the stackblitz: https://stackblitz.com/edit/angular-4rojla?file=src/app/chips-autocomplete-example.ts
Is there a way to loose the focus from the mat autocomplete after add so user has to click on the dropdown again?
