Live Search Macro is not working correctly with page excerpt

When using the live search on a page and selecting "page excerpt" on the additional information field the content is not being displayed correctly.

Steps to reproduce :

1. Create a brand new space called Search.
2. Now add the live search macro on the Home page of this space.
3. Edit the Live search macro;
4. in the additional information field select page excerpt
5. Now create a second page called This is My Bacon:
6. In there add the following test:

   This is not part of the excerpt
   

7. Then add the excerpt macro with the following:

   Bacon ipsum dolor sit amet strip steak frankfurter short loin, filet mignon porchetta landjaeger andouille. Strip steak sirloin prosciutto pork pork chop.

8. You can also use the following source code as well:

   <p>This is not part of the excerpt </p>
   <ac:structured-macro ac:name="excerpt">
     <ac:parameter ac:name="atlassian-macro-output-type">INLINE</ac:parameter>
     <ac:rich-text-body>
       <p>Bacon ipsum dolor sit amet strip steak frankfurter short loin, filet mignon porchetta landjaeger andouille. Strip steak sirloin prosciutto pork pork chop.</p>
     </ac:rich-text-body>
   </ac:structured-macro>
   

9. Now go back to Search space home page.
10. Search for Bacon.
    • Actual result:
      

You can see in above image the live search macro returned *"This is not part of the excerpt * together with the content of the macro.

As a expected result the live search macro should be showing only the content inside the excerpt macro as per selected option.
