Children macro is not properly live rendered and needs page refresh to display its content when in-place editing

STEPS TO REPRODUCE

1. Edit in-place a page that has children (eg. Sandbox)
2. Click on "Insert" Button (the "+" icon)
3. Click on Other Macros
4. Search for Children and click Select
5. Click Submit
6. Click Save & View
7. Click 'Edit' to edit the page again

EXPECTED RESULTS

The macro content (children of the page) is displayed in-place edit mode as well as right after the page is saved.

ACTUAL RESULTS

When in-place edit mode the macro displays:

macro:template

After the save, the page needs to be refreshed for the children to be displayed on the macro. However, if the macro is added in WYSIWYG editing mode, the content doesn't require a refresh after save.

The same behavior can be reproduced with 'Page Tree' macro.

Also, 'Template Macro' displays   in-place edit mode,  but does not require refresh after page save to display the content (tested with 'code.vm').

However, 'Tree Macro' displays different the content in-place edit mode and right after the page save, requiring page refresh (unlike when inserted though WYSIWYG edit mode).
