Annotation not working on pages without layout container

Hi Team,

Is there any restriction on aem page annotations, that it will work only when layout container is a wrapper container for the page?

I can only annotate on a page using aem OOTB annotation plugin, if the wrapper component on the page is ootb layout container.

Steps for annotate a page without layout container as wrapper component in it-

1. Create an aem page

2. Drag and drop any component, may be richtext

3. Try to annotate the page. - The add event for annotate won't get triggered. Unable to add annotation

Steps for annotate a page with layout container as wrapper component in it-

1. Create an aem page

2. Drag and drop General->layout container component onto the page

3. Drag and drop any component may be rich text component inside the layout container

4. Try to annotate the page. - Able to annotate successfully.
