It's not *that* uncommon to have a mouse that middle-clicks while scrolling.
Don't ask me for model numbers but I've seen the odd bug report over the
years about it and it's not always a worn-out switch.

Three-finger tap and (depending on configuration) a click with three fingers
on the touchpad or a click in the middle button area on the bottom or a
click with left and right button (or in button areas) simultaneously.
The old synaptics driver defaulted to 2-finger tap being the middle click.
