The "Show annotations" option breaks the suggest and the submit for the "Message Sender" macro

Steps to reproduce:

• go to Main.WebHome and create some annotations
• check the "Show annotations" option
• go to the "Message Sender" macro, select "User" in the drop-down list and type "Ad" in the input; the first suggested result should be "Admin" but instead you get nothing

If you manually enter "Admin" and click on "Share", you will be redirected to "Dashboard.WebHome?media=json". In order to make the suggest functional again you need to un-check the "Show annotations" option and refresh the page.
