VisualEditor find and replace tool gets the page to auto-scroll and moves the button away from the cursor.
- Go to https://en.wikipedia.org/wiki/Noise_reduction_coefficient
- Type Hz in the Find box
- Click on the "next" button (forward arrow) with the mouse
Observe: the window scrolls down and the find tool moves up. I would expect that just clicking again at the same place would click the same button, but the button moved away from the cursor. It happened to me several times and confused me each time.
