Not sure if it's a new issue, but Chrome now presents address field suggestions over iD's.
This only happens when selecting the address dropdowns in iD with a mouse. Navigating to the dropdown via keyboard and Alt-dropping still works.
Chrome version 71.0.3578.98
Share a screenshot please. I use Chrome and I haven't seen anything like this.
I was able to reproduce this by having an autofill address in Chrome's settings.


Ok cool, thanks @quincylvania .. iD does automatically add a bunch of options to our fields to avoid stuff like this. There might be another one that we need to add for this particular Chrome feature.
Turns out autocomplete="new-password" is the latest way to get around autofill on Chrome and Firefox. Safari still show autofill but it's relatively unobtrusive and autocomplete="off" wasn't working there either.
