Probably from the same weird block identified in #3085

plotly.js/src/plots/cartesian/dragbox.js

Lines 437 to 442 in 9bbe295

	// if the plot has scrollbars (more than a tiny excess)
	// disable scrollzoom too.
	if(pc.scrollHeight - pc.clientHeight > 10 ||
	pc.scrollWidth - pc.clientWidth > 10) {
	return;
	}

indeed "fixes" this bug. I'll try to get patch similar to #3085 merged in time for v1.44.0.
