Bypass time start refresh on rangemode

[jbval]

Hello,
I'm using the time picker in range mode.
I set a start time (ie 08:30), if i clear the end time, and start typing 1 (for 11:30 by ex) on the first input it change the start time to 01:xx.
I see that the effect come from date-time-picker-container in the timeSelected method but i can't find a simple workarround (disable check between start and enddate except on lose focus ).
Is there a way to do so ?
Regards,
