=== Transform Constraining ===

Bug #3733
Constraining on a perpendicular axis was broken on (half - 1) cases.
Silly oversight on my side which didn't turn out in the test case (moving camera in and out) and only appeared in front view (not side nor top) because of positive reasons.

Frankly, I still think translating an object perpendicular to the viewport is a bit silly, but now, at least, people can be silly in a predictable fashion.
