My guess is that bug 1381569 is the "culprit" for this behavior. Testing this issue on a more recent affected Nightly build (57.0a1 - 20170909100226), with the browser.newtabpage.activity-stream.enabled pref set on false makes the problem unreproducible.

Priority: -- → P3
Too late to fix in 63, but we could still take a patch in 65 and potentially, 64 beta.
