Comments: Prevent comment revert when context menu is open when Escape key gets pressed.

[yogeshbhutkar]

Description

Previously, in Firefox and Safari, pressing the Escape key while the context menu was open (activated by right-clicking) inside the comments form in the comments menu of wp-admin would close both the context menu and the comment form. This resulted in the removal of the written comment, forcing the user to rewrite it.

How was it fixed?

By using the contextmenu event, I was able to manage the state that controls the closing of the comment form when the context menu is open.

Screencast of the fix:

This looks good to me; just made a couple of minor changes to comments and the variable declaration pattern.
