Hi Andrew,
Thank you for reporting the issue.

Unfortunately, I didn't manage to reproduce the issue, so I forced to ask you for the steps to reproduce it and the version of Visual Studio you are using.
Can you record a screencast where the issue is present? You may use this software tool like we do.
Also, note that the Visual Studio version may be obtained at the Help\About Microsoft Visual Studio page, for example:
Here is the version of Visual Studio I am using currently.
After clearing the cache for the application and restarting my computer I am unable to reproduce the issue. Please close this ticket. Thank you.
Andrew, you're always welcome.
