Cosmetic issue - Tabs skipped

[Mastermind]

Try this: If 'Downloads', 'Wish List', 'Failed Downloads', 'Connections', 'Logging' and 'Files' is in autohide mode and you hoover from left to right over the tabs then this happens, on the first 3 tabs it's working like it shoud, but when you hoover over the 4. tab then it skipps to the 5. tab and than to the 6. tab, because the tab-text is shorter and the tab-position (from the 4. tab) ins't under the mousepointer.
