Clicking on "openByClickOn" element causes portal to hide and then immediately show.

[sam-aiq]

When the prop closeOnOutsideClick is true, clicking on the openByClickOn element causes the portal to hide, and then immediately show.

Yeah, that's a glitch. Do you want to create a PR? It should be simple.

Replace mousedown events with mouseup.

That's an awesome component. It will be very useful for my projects. Thanks very much! @tajo

fixed in v2.1.1

I have the same issue in 3.0.0. Replacing mousedown with mouseup looks insufficient as it's still triggered before click

Maybe you should check here that e.target isn't the openByClickOn element or its child

UPD: I can visually detect this issue only if portal content has css animations

And I guess that most people would like the portal to hide in this case, not to keep being shown (one can achieve this with beforeClose={(ev, cb) => setTimeout(cb, 0)} though)
