Struct CustomElementReactionStack 

pub(crate) struct CustomElementReactionStack {
    stack: DomRefCell<Vec<ElementQueue>>,
    backup_queue: ElementQueue,
    processing_backup_element_queue: Cell<BackupElementQueueFlag>,
}

https://html.spec.whatwg.org/multipage/#custom-element-reactions-stack

Safety

This can be shared inside an Rc because one of those Rc copies lives inside ScriptThread, so the GC can always reach this structure.

Fields

stack: DomRefCell<Vec<ElementQueue>>

backup_queue: ElementQueue

processing_backup_element_queue: Cell<BackupElementQueueFlag>
