(1) and (2) take me to the top of this page. (3) takes me to a new tab, same page, but scrolled down to the particular post. [Your results, thus confirmed.]

- which is to say, the reader can now see which particular message in the thread was being referred to.

Open the Settings app (Win+I keyboard shortcut). Click the “Devices” category. From the left sidebar, click the “Mouse” page. Toggle the “Scroll inactive windows when I hover over them” option to “off”.

Nice thinking, but that's not it - it was already set that way.

(Also) At that point, particularly after a click to try and stop the scrolling, it is the active window.

Just getting the scrolling to stop long enough to click somewhere, before it scrolls away again, is such a PITA! {Mouse != touch screen!}
