struct ScriptMemoryFailsafe<'a> {
    owner: Option<&'a ScriptThread>,
}

Expand description

In the event of thread panic, all data on the stack runs its destructor. However, there are no reachable, owning pointers to the DOM memory, so it never gets freed by default when the script thread fails. The ScriptMemoryFailsafe uses the destructor bomb pattern to forcibly tear down the JS realms for pages associated with the failing ScriptThread.
