In calendar when readonly is set to false and user can manually enter date, this check doesn't work properly when date format is set to YYYY-MM-DD. When you try enter eg. 2022 calendar automatically set different date.

It works properly when below function will be change from:

var keyUpControls = function(e) {
if (e.target.value && e.target.value.length > 3) {
var test = jSuites.calendar.extractDateFromString(e.target.value, obj.options.format);
if (test) {
obj.setValue(test);
}
}
}

to:

var keyUpControls = function(e) {
if (e.target.value && e.target.value.length == 10) {
var test = jSuites.calendar.extractDateFromString(e.target.value, obj.options.format);
if (test) {
obj.setValue(test);
}
}
}

or dateformat.length instead of 10.
