Let me @mention myself

I may happen to have a different username in Bitbucket than I do across other Atlassian products. When this is the case, or when I forget my username, when I attempt to mention myself in a comment in Bitbucket, I expect to see myself as a suggestion as I begin to type.

The suggestion isn't occurring for me, however--even if I type my entire user name. I think it worked before, but it no longer works. Is the regression intentional?
