Issue title username layout problem
Summary
The title of an issue includes the avatar/name of the user that reported it (… by ). When the browser window width is small, the avatar and name is replaced by the username. The text "… by @robmv" appear as "… by@robmv", notice the lack of the space between the by and the username.
Steps to reproduce
Visit any issue page, reduce the width of the browser window until the avatar and user full name are compacted to a reference to the username. The title will be shown as "… by@robmv"
Expected behavior
the title should show as "… by @robmv" , notice the space after the by
Relevant logs and/or screenshots
When the browser window width is large
When the browser window width is small
Possible fixes
Not sure why the space isn't on the generated output because it is on the template at https://gitlab.com/gitlab-org/gitlab-ce/blob/master/app/views/projects/issues/_issue.html.haml#L39
Notes
I noticed this problem because when using Ghostery, gravatar links are removed by default and the text always lack the space. Noticed the problem still happen when there is no extensions running (Firefox and Chrome) but only when the window width is small, when the avatar is show the avatar spacing balance the lack of the space after by
