DateInput popover does not close on tab blur

[chiubaka]

Environment

• Package version(s): @blueprintjs/core 3.3.0; @blueprintjs/datetime 3.1.0
• Browser and OS versions: Firefox 61.02 (64-bit); macOS High Sierra 10.13.6

Steps to reproduce

1. Create a tabbable form including a DateInput.
2. Attempt to tab through the form.

Actual behavior

When hitting tab to move from a DateInput to the next input, the DateInput's calendar popover does not dismiss. Interestingly, if shift-tabing backwards, DateInput does dismiss the popover.

Expected behavior

As we are no longer focused on the DateInput, it seems like the DateInput's calendar popover should dismiss.

Possible solution

Close the popover when tab is pressed in a DateInput.

as a workaround: pass inputProps: {
onKeyDown: function( e) {
if (e.which === Keys.TAB && !e.shiftKey)
this.refs.yourref.setState({ isOpen: false })
}}

inputProps:onBlur does not work correctly with opened daypicker, it seems to fire before value is ever set.
