Understanding "NYC Uber Rasterizer" demo's inconsistent zoom behavior

Like many community members I occasionally find myself looking at the dash app gallery from time to time for inspiration. One thing I have never understood is the zoom behavior on the Uber Rasterizer NYC demo: https://dash-gallery.plotly.host/dashr-uber-rasterizer/

In my browser I find that once I zoom in far enough to reach the MapBox plot, if I zoom any further, the chart resets to the zoomed-out raster plot once again as if it was performing a hard reset. Do other users experience this issue when checking out this demo, or when using their own rasterized data plots?
