As you might know, pinning a Menu (like the WorldMenu) slightly
changes the size of the menu.

This was somehow caused by initialising AlignmentMorphs

with an extent 1@1 in #newRow.

I removed that line, th fix is in Pharo 40 059. (issue 13433).

As the morph layout computation is pretty complex this may

cause some unforeseen issues.

just to be warned :)
