> nsClipboardCommand::IsCommandEnabled
now returns true unconditionally after Firefox 41 (bug 1012662, bug 1162952)

My script depends on the return value of `nsClipboardCommand::IsCommandEnabled` no longer works, can I find any alternative solution to it?

Code snippet:
> try {
>     var controller = top.document.commandDispatcher.getControllerForCommand(aCommand);
>     if (controller && controller.isCommandEnabled(aCommand)){
>         controller.doCommand(aCommand);
>     } else {
>         DoSomethingIfItsNotAvailable();
>     }
> } catch (e) { }

If there's a need for this that should probably be standardized first, e.g., at https://github.com/w3c/clipboard-apis/issues.
