Site works OK, Mouseover pops up but won't go away

One of the most bothersome things in any website is the over use of mouse-over (MouseEnter).

This is when one just moves the mouse over a thing, and a window pops up in anticipation of pressing the left button.

I find this annoying in 99% of cases, but it is doubly so when the window pops up and doesn't go away.

Programmers seem to feel the need to display their prowess by adding features until websites grinds to a halt.

In particular, when I slide my mouse over my name (near the top right) or inbox, or alerts a flyout pops up.

After moving the mouse away from the name (or flyover) the little window doesn't go away.

To get rid of it I must actually click elsewhere on the page.

Of course, once in a while I accidentally click on a link and I am taken off to wonderland.

#1 MOST flyovers are simply a nuisance. If I want something, I can click on it.
#2, If you insist on using a MouseEnter, there should be a timeout. no more then 3-5 seconds.
#3, ALSO, there are MouseEnter, and MouseLeave commands, it seems lazy programmers only use the MouseEnter and don't put the time programming the MouseLeave part.

Thanks for reading my vent.

I know what he's talking about, and see it happening on a Win7 equivalent (Server 2008r2 Remote Desktop session.)

 

Since he mentioned it, noticed it's also happening in Chrome on a MacBook running High Sierra. Screen cap below. As the cursor passes over any of the links in the upper right corner, it pops up and won't go away until I click on a blank part of the screen.
