iCloud Passwords Chrome Extension introduces 500ms lag on <input> focus

When the iCloud Passwords Chrome extension is on, there is a 400-500ms lag between clicking on a non-password <input> field and the UI reflecting any changes made by a .on("focus") jQuery listener.

When the extension is disabled, there is no lag.

See below the performance profiles for the same 4 click events.
