Saving: encountered a possibly infinite loop

[Paula-Kli]

Describe the bug
Somehow maybe something with the graph or something with the tree sequence but not quite sure makes:

Error saving world: Error: Stopping serializer, encountered a possibly infinit loop: attributeConnections.0.targetObj.attributeConnections.2.varMapping.scrollbar.submorphs.0.attributeConnections.0.targetObj.submorphs.0.submorphs.0.submorphs.0.timelineLayer.submorphs.1.sequence.attributeConnections.0.targetObj.attributeConnections.6.targetObj.attributeConnections.1.targetObj.attributeConnections.1.targetObj.attributeConnections.1.targetObj.submorphs.0.submorphs.1.attributeConnections.5.targetObj.attributeConnections.1.targetObj.timelineLayer.container.submorphs.2.submorphs.0.submorphs.1.sequence.attributeConnections.2.targetObj.submorphs.1.submorphs.10.target.attributeConnections.4.targetObj.container.attributeConnections.0.targetObj.submorphs.0.submorphs.0.submorphs.0.submorphs.1.target.morph.attributeConnections.6.targetObj.inspector.submorphs.1.attributeConnections.1.targetObj.attributeConnections.1.targetObj.submorphs.0.submorphs.0.attributeConnections.0.varMapping.source

Steps to reproduce

• Open a new interactive
• Cut cloud morph from skye sequence
• Paste cloud into tree sequence
• Insert a new lottie morph into skye sequence
• Try to save the editor

Additional context: Closing all open sequence view tabs allows to save again.
