Optional throbber

First, I love the new look and feel of the search autocomplete dropdown. I'm using it with the Olivero search bar and it just looks great. I've noticed there's occasionally an extended delay in between the minimum number of characters needed to activate the autocomplete being entered and the results showing - that's *just* long enough to potentially not be clear to the user that results are actually incoming - that I'm wondering if it's possible to add an optional throbber as soon as the minimum characters are entered, as a simple visual cue that results are on their way.
