Different from the comment in `EditorCommands.h`, editing commands and editor commands are instantiated for each editable document or each `HTMLInputElement` or `HTMLTextareaElement`. Therefore, even though they are stateless, we allocate too many instances of them. We should make them singleton classes to reduce the footprint and save runtime allocation cost.
