If the team name contains a space, the name shows up truncated on the team name input field on the settings page.
For example: Teams in Space will just show up as 'Teams'
The team name is showed correctly anywhere else on the site though
If you enter a name with spaces in https://bitbucket.org/account/user/<team user_id> and click 'Update profile', the name shows up complete in that field.
However, if you navigate to another page and then go back to https://bitbucket.org/account/user/<team user_id> again, then the name shows truncated.
