Graph Adjuster tab, 'Max' entry box permits values less than min to be entered, although it does not apply them

There are several ways to make the 'max' entry box permit a lower number to be entered, but then will not apply it. The behavior SHOULD be that every time the enter button is pressed - no matter what - the number is checked and set to a number slightly higher than min. The same behavior is expected in the min box. But it is currently very easy to 'trick' these boxes into permitting wrong numbers, and not correcting them (or applying them) when the enter button is pressed.

Open a graph, go to graph adjuster, y-axis by value checked. Set min to 10, enter. Now set max to 5, enter. The first time, it corrects to 10.1, and sets graph. Now enter 5 again, it accepts 5 into the box without correcting and without changing graph. NOW set min to 0, graph changes to chow 0 to 10, although '5' is still in the max entry box. Click on max box and hit enter (5) - this time it registers the 5 and corrects. Now enter 10 in the min box - igb corrects is to 4.9. Reenter 10 - and it is now 10, uncorrected, and the graph does not change.
