#37126: Shiny Updates: plugin updates fail from the update-core.php details modal

Component:  Plugins       |    Version:  trunk
 Severity:  normal        |   Keywords:  needs-patch
  Focuses:  javascript    |
--------------------------+-------------------------
 To reproduce, go in `update-core.php`:
 - click the "View version details" link on any available plugin update
 - the details modal opens
 - click the "Install Update Now" button
 - nothing happens, the browser console reports a JS error

 On Firefox, the error message is a bit more clear and it says that
 `$message` is undefined.

 Quickly looking at the `updates.js` code, maybe when clicking on
 `'#plugin_install_from_iframe'` the check for the 'update-core.php' window
 parent should be reintroduced when returning early before
 `event.preventDefault()`.
