Top bar mouse clicks slightly off

[egmont]

In the top row, click on the space character immediately before the "File" label.

Actual: The "Left" menu opens.

Expected: The "File" menu should open, since when clicking on "File", this space character on its left is also highlighted.

Or, taking into account the dropdown menu's location (including its border), maybe even the second space character to the left could open this menu.

Same goes for all other top row entries of course, and also for mcedit.
