This is a Window-10 touch device specific regression issue, broken in M-66 series, and below is bisect info :

Manual Bisect:
Good Build:66.0.3350.0(Revision:537343).
Bad Build:66.0.3352.0 (Revision:538313).

Unable to provide bisect through per-revision script, as chrome builds for #66.0.3357.0 are getting crashed while bisecting on Win-10(Touch device)OS.

Hence, providing through old bisect script(chromium builds).
Narrow Bisect:
You are probably looking for a change made after 537519 (known good), but no later than 537521 (first known bad).
CHANGELOG URL:

Suspecting: r537521?
