configuring a spinner like that (using min and max) will lead to mixed custom and default error message

<spinner constraint="min 5 max 10:should be between 5 and 10 (incl.)"/>

input value <5 -> custom error message is shown
input value >10 -> default error message is shown

workaround:
specify the min and max error message separately

<spinner constraint="min 5:should be between 5 and 10 (incl.), max 10:should be between 5 and 10 (incl.)"/>
