      Description

      The attached example usually crashes with one of the three call stacks below when creating the view the second time, arranged in the order of most common to least common. Rarely it doesn't crash on the second create, but then it will do so on the third create.

      This issue causes node preview in QDS to crash the puppet.

      The pending fix: https://codereview.qt-project.org/c/qt/qtquick3d/+/319719 doesn't affect this issue.
