Status, widget and viewfile macros on the page blink when I Undo or autoformat

• Add some macros with custom placeholder to a page.
• type some text
• undo. The placeholders will flash.
  • Or autoformat e.g. type *asdf* and the placeholders will flash.
  • Press enter immediately after the macro.

This is limited to SOME of the macros with customer placeholders.
Flashing: Status lozenge, view file macros (eg embedded ms office documents), widget connector (youtube, twitter, etc.)
Not flashing: Embedded JIRA issue.
