 **Description**: When new updates are available, I upgraded to the new
 version but after the upgrade successful, I still see the upgrade version
 and after that WordPress started working very slow. Any operation
 performed on the platform will take more time to load and sometimes it
 comes up with "connection time out" error too.

 **Steps to reproduce**
 1. Check for update
 2. update your WordPress version from your site to version 5.2.1
 3. Route to the dashboard, where you will see update button to version
 5.2.1
 4. Perform any operation like (user info, plugin page, widget page) it
 takes time to load and sometimes it throws "connection time out".

 **System Info:**
 System: Windows, Linux
 Browser: Chrome 74.0.3729.131 (Official Build) (64-bit)
