Some macros don't execute properly when editing the source of a page in the inplace editor and saving directly from there

Steps to reproduce:

1. create a page with the create page form
2. save the page, empty
3. from view mode, enter the edit mode, using the default editor (in-place and realtime)
4. switch to source editing, from the rich text editor button
   •  at this point an information box will say that the realtime editing mode was left, which is alright, expected and normal
5. type or paste a liveData macro call, for example:

   {{liveData
     id="users"
     properties="_avatar,doc.name,first_name,last_name"
     source="liveTable"
     sourceParameters="className=XWiki.XWikiUsers&translationPrefix=xe.userdirectory."
   /}}
   

6. click save and view

Expected result:

• edit mode is exited and a livedata table loads in view mode for the page

Actual result:

• edit mode is exited, but the page only displays a spinner indefinitely (and the table never loads):

• after a refresh, the page displays properly, as expected
