It’s a result of having Last Pass as a plug-in for the browser. If you don’t want Last Pass to manipulate the browser, you need to remove it as a plug-in. I don’t think it’s anything we can control; those elements need to be HTML
<input> elements, and Last Pass looks for inputs of certain types and assumes you want to use it everywhere. Please don’t treat this as a definitive answer, but this is how I remember it as explained to me when we encountered it here. If you open an Incognito browser window, I believe you’ll no longer see the Last Pass interaction. It’s possible that using a different Chrome profile would also remove them as Last Pass is tied to a user profile.
