Autofill UX: Ability to close suggestion box

Sometimes 1P gets it wrong and pops up an autofill box by mistake. I'm not expecting 1P to be perfect on every possible web site, so I'm not asking to be fixed for this web site., What I'm asking is for a way to close the autofill popup without leaving the field I'm in. Here's an example:

The 1P pop up is popping up on a mailing address field that has autocompletion by the web site, and 1P is blocking my view of the site's suggestions, preventing me from choosing the correct item on the site's list. There seems to be no way to close/hide the 1P popup other than to leave the field, which causes the site's own drop down to disappear. If I go back to the field, then the 1P popup reappears over the site's own dropdown list again. So 1P always blocks my view and I have to click a random item to see if I chose the right element.

Sometimes I get a "No Items to Show" popup like this, other times I get a list of random 1P record shown which further obstructs my view of the site's suggested items.

I'm asking if 1P could add an "X" button on the top right to hide any field popup like this so that we can just dismiss 1P if its autofill does not apply. I know that I can go to the browser extension and disable autofill, but that's too many mouse clicks for doing something this simple, plus it's a long-term change (unless I remember to re-enable autofill afterwards). All I want to do is close the suggestion list that pops up.
