I can confirm that this is really an issue. I am encountering the same after using 3 dropdowns in a Header bar. It's really inconsistent. Sometime the menu closes when another one opens sometimes it doesn't.

@annjawn please make sure that you're using the latest version.
The described issue comes from the closeOnBlur prop, I need to perform an additional checkes, it can be expected behaviour.
I can confirm that this issue not only happens when using Subcomponent API Dropdown.Menu but also using shorthand with options. I just updated the module about an hour ago hoping for a fix but the issue persists. As a workaround I had to manage individual states using open, onOpen, and onBlur for each <Dropdown> component.
This could be related to #3006. Multiple popups have the same issue. Perhaps this is an event handling problem in EventStack.
If it helps at all, the process is actually _very_ consistent, exact steps:
This issue has been stale for a while. Is anyone looking into it?
Yes, I've been investigating on weekends as available. There is a related issue with opening multiple popups. There is something possibly awry in EventStack, or even Portal. More eyes are very welcome.
I did a small investigation and described it on this issue.
I could work on a solution if someone could tell me the right direction to take.
Confirming #3148 has fixed this issue. 馃帀馃帀
