Subject: [PATCH] Fix crash when a custom material / effect shader variable
changes
We ended up deleting valid commands in cases where a shader variable
changed without the custom material or effect being deleted. Just redo
the to-be-deleted command list in updateSpatialNode instead of deleting
it.
Fixes: QTBUG-112969
