Added comment: I tried Using F2 to zoom out and with the same nightly as above. That does not cause this problem, it stops at 0.3 not only in number, but also in size and does not jump (provided mouse cursor is left in the center). So I can only confirm the bug when mouse (wheel) is used to zoom out, intentionally or accidentally.
