Date range input selection will close the whole dialog

[gasolin]

Environment

• Package version(s): 3.0.1(core) 3.0.0(datetime)
• Browser and OS versions: firefox 60.0.2 / ubuntu 16.04

Steps to reproduce

1. Put a Date range input inside dialog component, like

 <Dialog
  icon="calendar"
  onClose={this.handleDialogClose}
   title={intl.formatMessage({ id: 'timeframe.custom' })}
   autoFocus
   canEscapeKeyClose
   canOutsideClickClose
   enforceFocus
   usePortal
   isOpen={this.state.isOpen}
  >
          <div className={Classes.DIALOG_BODY}>
            <DateRangeInput
              allowSingleDayRange
              closeOnSelection
              formatDate={dateFormat.formatDate}
              parseDate={dateFormat.parseDate}
              onChange={this.handleRangeChange}
            />
           </div>
</Dialog>

1. select date with Date range input

Actual behavior

1. when a date is selected, the whole dialog is also closed

when showing same date range input without dialog, it behave normally

Expected behavior

1. when a date is selected, the whole dialog is keep showing

Possible solution

The dialog and Date range input might share the same event or property to close the dialog/popup.
Should use the separate one so the behavior won't interfere
