Grabbing an offscreen window leads to infinite loop if View3D has importScene

Grabbing an offscreen window leads to infinite loop if View3D has importScene. The first grab returns fine, but the second grab goes into an infinite loop. Looks like there is a loop in the child list of the QSSGRenderLayer.

See the attached example to reproduce.

This blocks offscreen rendering of 3D edit view qmlpuppet in QDS.
