I am able to reproduce this. Indeed the screencast does not show the problem, because it has fairly low frame rate. Repro: Zoom-in the page gradually. Find the threshold zoom level at which the toolbar transitions from wide to narrow mode. A flashing horizontal scrollbar is shown at the bottom of the page momentarily, right before the toolbar collapses (causing the scrollbar to disappear). Fix candidate at https://chromium-review.googlesource.com/#/c/chromium/src/+/879598.
