Show issue number/merge request number in the beginning of page title

Prior to version 7.11 I could see issue number in front of the tab and always select correct tab. Now, for some unknown reason, you decided to decrease usability of GitLab by moving issue number into end of the page title, where it's not visible.

Please reconsider moving it back to the front.

Perfect title should be:

• !xxx - title... - for merge requests
• #xxx - title... - for issues
• $xxx - title... - for snippets
