[JENKINS-76002] String comparison in JS when numbers are expected

[jenkins-infra-bot]

jenkins/war/src/main/webapp/scripts/hudson-behavior.js

Line 828 in f49b4b9

if (min <= max) {

compares min and max, which are strings.

"5" would be greater than "10" here, because they're compared by character, not numeric value.

To reproduce, compare form validation behavior of e.g.

<f:number min="10" max="20" clazz="positive-number-required" />

and

<f:number min="5" max="10" clazz="positive-number-required" />
