Thanks for reporting this, I can confirm the UI problem. However, Mojira is built on a platform called Jira and these fixes cannot be resolved by us but by the software developers. I'll close this bug as there is nothing that Mojang can do to fix it, but if you'd like to have it fixed I suggest you report it directly to Atlassian and the Jira team here.
