There is a strange behaviour when clicking on the lower part of the URL bar - it appears that half of the "returning from left-aligned edit mode to centre-aligned view mode" animation is played, even though the end state doesn't change. This means each time you click, you get the same animation, but nothing changes.
Video speaks a thousand words:
Each time the animation cycles, I had clicked the touchpad. You should be able to gauge the cursor position from the video. It doesn't appear to be too precise or require pixel accuracy, as I triggered this on second attempt a few times.
