Never show two flyouts at once

[nacin]

There is an intentional (and slight) delay until a flyout gets hidden. But the moment another one is opened, the delay should be terminated and the flyout should immediately be closed. Two flyouts should never show at the same time.

This bug has probably contributed to the occasionally voiced perception that the dashboard is a bit slower in 3.3.

I'm not able to reproduce this bug. I move from one main menu item to another very quickly (moving mouse pointer vertically) and are not able to see two flyouts at once. Or may be for 1/100 of a second, wich could be a browser issue to me. Hardly a contribution to a perception of a slow dashboard. Suggest "worksforme".

knutsp, just hover fast over media and links again and again, then you can see it.

After extensive testing I am able to move from Links to Media and back, without the Links flyout closing and the Links flyout being present above it for a split second or less.

I can hardly see this as a bug, even a very minor one. If I am wrong, severity less than trivial.

+1. It's only a slight delay but it gives the impression of lag.

I have tested this on my setup and was able to reproduce, here is a video:

Patch looks good, but what do I know. koopersmith?

19575.patch looks good here too, makes the flyouts a bit snappier.

In [19647]:

Immediately close a flyout when opening another one. Prevents brief occurrence of two flyouts at once. Props SergeyBiryukov. fixes #19575 for trunk
