Photo is of the search bar bug. You can see the typed web address overlaying the address initially typed. The search bar becomes unresponsive in this state.
Video is a realtime of the bug. Unfortunately, it's not reliably produced, so the video doesn't cover the moment when the bug was first encountered; I slid right to left on the search bar to open a new tab, and that's when it happened. Recent updates seem to have made it less common, but it still pops up.
