When adding a macro inside the Rich Text Editor, TinyMCE is removing the <!-- startUmbMacro --> <!-- endUmbMacro --> tags from my macro when saving. On the original save it works fine. But if you try to save it again you get the error listed below.

Can you stop TinyMCE from stripping the comment tags? Or if the comment tags are not really required for the macro to function why is umbraco throwing the error?

I cannot ask my users to delete the macro and then put it back every time they update the content or a property value on the page.

I'm on Umbraco version 4.7.0 and .NET version 4.0. I have made no customizations to TinyMCE at all.

Thanks for any help you can give on this.
