I believe that the root cause is the same for both issues and it’s the symptoms that differ. My interpretation for root cause, after have reading the other thread, is that the scroll threshold is too low. Both comes down to the threshold used to identify when a user wants to start scrolling or just holding still.
In this, current report it means that the browser starts scrolling too early, instead of marking text or activating the context menu and in the linked post it means that the browser tries to scroll the page, instead of activating the link.
