null pointer exception when editing dashboard with open panel menu

[nreese]

Open a dashboard with one or more panels. Open the context menu for a panel

Without closing the panel menu, click edit. An error is thrown

This is the result of an EUI bug in EuiContextMenuPanel. updateFocus method calls a ref inside requestAnimationFrame. The component is unmounted before the contents of requestAnimationFrame gets called so there is null pointer exeception.

Closing since the problem was introduced in EUI 3.0.1 and kibana is still on EUI 3.0.0. EUI releases 3.0.1, 3.0.2, and 3.1.0 should all be avoided because of this problem.
