I don't know. I'm equally in the dark as you are :-) I didn't test with previous versions, but I only saw this occur recently, too. It has prompted me to move to Firefox, which doesn't have the bug (but other Webkit-based browsers do).

It spontaneously jumped to the top of the page when I continue scrolling downwards (using a touchpad). As of a July 1 update to chromium-browser:amd64 (50.0.2661.102-0ubuntu0.16.04.1.1237, 51.0.2704.79-0ubuntu0.16.04.1.1242) chromium-browser now has the same bug! To reproduce this, I scroll half-way down a page (using a touchpad?) and then click on something (e.g. blank space, which has no effect, or ctrl-click on a link to open it in a new tab) with a mouse button. Next, as soon as I touch the touchpad to continue scrolling, the page jumps to the top. Makes browsing near impossible. Very frustrating to have this bug arrive at this browser after I already left Chrome (whose latest version on Ubuntu also still has this bug) to avoid it.
