Zoom Menu on Mac OS-X is not working when called with keyboard shortcuts

[TheFive (thefive.osm@…]

What steps will reproduce the problem?

1. Start JOSM on Mac OS-X
2. Choose cmd + to Zoom in or cmd - to zoom out

What is the expected result?

Expected Result is, that the map goes to the next zoom level (which is done, if you call the menu not with the keyboard)

What happens instead?

The View (Ansicht) Menu is shortly inverted to black/white, so the keyboard shortcut seems to work, but it is not zoomed.

Please provide any additional information below. Attach a screenshot if possible.
