(alt)Search/ Modify Doc Links in Rich Text

There is something very wrong with this page when copying the content or trying to insert/replace images. (Also could not find the original images from site)
Confluence server suddenly had trouble loading the page and hangs.
This happened on two separate dates in May and June.
