This can cause panics if a GC occurs after the ScriptThread code has cleaned up the TLS:

servo/components/script/dom/worklet.rs

Lines 159 to 164 in dae4943

impl Drop for Worklet {
fn drop(&mut self) {
let script_thread = ScriptThread::worklet_thread_pool();
script_thread.exit_worklet(self.worklet_id);
}
}
