The Restore command does not restore the selected version. It sometimes restores the "latest" version instead. The Restore button is only enabled when you select a list item but the command does not act on the selected item.

To reproduce, first build a version history:

1. Edit a page. Make a change you that can identify later, for example change the first word on the page to "Monday".
2. Activate the page. Set the workflow comment to "Monday".
3. Repeat two times using "Tuesday" and "Wednesday". Now you have a basic version history, see version-history.png
   
   

Then restore the first version:

1. Select the first version (Monday) and click Restore.
2. The system creates a new version of the content and adds it to the list, see 1st-versioning.png
   
   

Issue: The system displays a message "Successfully restored latest version", see message.png. But that's not what you selected. You selected the first version (Monday).

Restore again:

1. Select Monday again and click Restore.
2. This time the system versions the content you selected (Monday) and applies the correct workflow comment, see 2nd-versioning.png
   
   

The problem is that the system responds differently to the same user action. First it versions the latest version (Wednesday), then the user-selected version (Monday).
