Description
Make
Menu
components more efficient when used in large numbers by only registering a single set of event listeners on thedocument
to track whether a user is using a keyboard or a mouse.This properly fixes #1239 and #1139.
I also saw that a similar change was attempted in #1252, but I'm proposing a much simpler implementation here.
P.S. I did read through the discussion in #1239, but we unfortunately do seem to be running into some performance issues due to having a huge number of React components including Menus on the page. While I agree that this is an issue in and of itself, I also think that it's great for UI libraries to be efficient and be able to scale well with a large number of component instances.
