AP/PM mode breaks mask for TimePicker

[dvd73]

Hi When I use "hh:mm A" format along with mask I get follow problem with input mask for TimePicker

I use follow options for TimePicker:

TimePickerOptions: {
            datepicker:false,				
            format: 'hh:mm A',
            formatTime: 'hh:mm A',
            mask:true,				
            step: 15,
            validateOnBlur: false
        }```
It is impossible to set mask = '12:59 [APap][mM]'
Please  help.
