Adittional escape character added when bold and strikethrough surround a macro

Switching between wiki markup editor and Rich editor will cause extra escape characters added to pages when the bold and strikethrough surround a macro

Steps to replicate the problem:

1. Create a page in a space
2. Switch to wiki markup editor
3. Copy the following code:

   -{macro}-
   *{macro}*
   

   NOTE: You will need to change the

   {macro}

   to some other syntax which fits your environment

4. Switch to Rich text Editor and return to wiki markup again
