"Close comment reply form on Escape" feature causes accidental sabotage

[yellowafterlife]

This is kind of like #54548, but in a different scenario.

Here's a thing that happens every now and then:

• I write an in-depth reply to a comment.
• I decide to double-check spelling, so I press Menu to open the context menu.
• "Check Spelling" turns out to be already on, so I press Escape to dismiss the context menu.
• ​This snippet catches the "keyup" event, closing the comment reply form and dismissing everything that I just typed.
• I let out a disappointed sigh and write a much shorter reply.

But there's more! This only happens in Firefox - in Chromium-based browsers the keyup event doesn't seem to be triggered at all (?)

Thanks for reporting this! That's certainly irritating. I attempted to reproduce this following your instructions, but wasn't able to right away; however, I'm going to milestone this for 6.8 for further exploration to try and resolve it.

I was able to reproduce the bug spotted by @yellowafterlife. I confirm that this occurs only in Safari and Firefox; as pointed out by the author, it works as expected in Chromium-based Web Browsers.

Here are the simplified steps to replicate the same.

1. Open a Web Browser and navigate to the Comments Menu.
2. Click on reply on any comment.
3. Type something and right-click within the comment box to open the context menu.
4. Now hit escape.

On Chromium-based Web Browsers, just the context menu would close. However, on Safari and Firefox, the context menu and the comment box closes which also wipes off the earlier written comment.

### 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:
