Image Caption is not saving when editing in-line with "Page edit" and not direct to the "Edit Image" page

Problem/Motivation

When editing Image caption within "Edit Page content" (not on the "Edit Media" config), the caption is not saved when saving the Page/node.

Steps to reproduce

1) Edit page content
2) Edit image caption within the page content
3) Save the page
4) View the image caption and it's not updated

Proposed resolution

It is ideal to just completely disable editing of image caption within the page content and just do all the image updates with in the "Edit media" config.
