Well, I'm not sure whether it's related each other though, it stays with sleeping for IPC, the tree look like:
```
+ mozilla::detail::ConditionVariableImpl::wait
  + mozilla::OffTheBooksCondVar::Wait (34%)
    + mozilla::TaskController::GetRunnableForMTTask
    + mozilla::TaskController::ProcessPendingMTTask
  + mozilla::detail::ConditionVariableImpl::wait (0%)
     <snip>
       + (anonymous namespace)::ClipboardDataSnapshotProxy::GetDataSync
         + mozilla::EditorBase::GetDataFromDataTransferOrClipboard::::operator()
           + mozilla::EditorBase::GetDataFromDataTransferOrClipboard
             + mozilla::EditorBase::GetDataFromDataTransferOrClipboard
```
So, it could be caused by a performance issue of clipboard access or creating the data transfer in the main process. Maybe, edgar may have some ideas.
