Certain image visually truncated when zooming larger than 100%

Earth_temperature_timeline : is truncated [made transparent] when zooming larger than 100%.

Is OK at 100% zoom. Is almost OK at 110% scale. Starts failing massively at 120% scale.

Is there a height limit when zooming/scaling?

Reproduce the issue with Earth_temperature_timeline at 100%, 110%, and 120% zoom, recording when the image becomes truncated or transparent. Trace the relevant zoom and image-rendering behavior, then verify that the image remains fully visible at the reported scales without regressions at 100%.
