@krojack If the window is maximised, there is no problem as one can simply click on the very top of the tab, which has infinite height. Make sure that you have enabled this checkbox in Settings, Tabs, Tab Display:Remove Tab Spacing in Maximised Windows

If you don't use maximise windows, then I agree that it is difficult to point and click accurately.
Wider Pinned Tabs might be another solution to this problem.
