JetBrains: Esc key doesn't work in the popup

Created by: vdavid

Context

In the "Find in Files" window, Esc key closes the window. We expect our popup to work the same

Problem

When the web view is focused, the Esc key does nothing. (When a Swing component is focused, it closes the popup.)

Solution

Recognize Esc key presses inside the web view and trigger closing the popup.
