Dropdown date picker is not closing fast enough

[labros-zotos]

I have two input fields(one next to each other) with dropdown date picker enabled for both of them.
When I click on one of the fields the dropdown date picker is displayed as it is expected.

However when I click on the second field (while the date picker of the first one is still open) there is a delay in closing the first date picker. As a result two date pickers are displayed for half a second one on top of the other.

Has anyone else encountered this issue? Is there a delay somewhere in the source code that I cannot find, maybe bound to a click or focus event?

Thank you in advance.

Try to hang the handler on the container and check that the click is made outside it
