Bug: disappearing region when in GeoGebra Materials

Not a Problem
The region disappears only in GeoGebra on-line Materials: https://www.geogebra.org/m/aqcmjgtt (bug happens with Firefox, Chrome and Microsoft Edge).
The problem does not happen when the construction is loaded in GeoGebra Classic 5 and 6.
