Description Matt Woodrow 2023-09-21 17:51:42 PDT 
We have a limit on backdrop layers, implemented in GraphicsLayerCA which disables the backdrop layer if we have too many.

This doesn't stop the backdrop structural layer from being created though, and it also doesn't stop ancestor RenderLayers from becoming composited.

We should probably try to determine the limits at the RenderLayer level, so that we can avoid all the other layerization changes (all which can use extra memory).
