Add the ability to add macros inside the info panel/s

Currently, when you try to add some macros inside the info panel macro, it gets thrown outside the panel and gets added right below it.

It would be nice to have an ability to add more macros inside the panel macros for more layout options.

Below are some of the macros that are confirmed to be not working inside the info panel macro:

• Expand macro
• Files & Images macro
• Excerpt include macro
• Code block macro
• Table macro
• Content by label macro
