Overlays are not closed on esc key after clicking or focusing inside the overlay component

I guess that the title does explain the situation.

Even canEscapeKeyClose prop is set to true, after you click on any element on the drawer, making it the event receiver, the drawer doesn't close on esc key press.

This applies to all overlay components, including Dialog, Popover2, and Drawer. I'll update the title.

@adidahiya Not sure if it helps, but setting tabIndex={0} on the child component to allow focusing it might fix it.

I can no longer repro this bug, but now we have another related one: #6399
