Wp-calypso: Syntax Highlighter Block: end tag closing bracket is improperly converted to encoded bracket

[supernovia]

Steps to reproduce

1. Add a Syntax Highlighter Block
2. Paste code for an HTML image
3. View the results

What I expected

I want the document to display the correct code, like this:

<img src="x.gif" alt="x" />

What happened instead

We display this:
<img src="x.gif" alt="x" /&gt;

Browser / OS version

Any

Screenshot / Video

At first I thought the images must be broken because the user was copying and pasting and the images didn't work. Then I realized it's actually the way our code displays. D'oh.

After multiple reports are there any plans to finally fix it by addressing the underlying defect in the code?

I have another user reporting this in 14220674-hc. Are there any alternatives? Also, seems like the same issue is reported in #34826

I have another instance here 2394809-zen. In this case I suggested using the regular code block or the pre block as a suboptimal, but practical, workaround.

I'm seeing the same on our own support documents:

Changing those blocks to "Code" for now until this bug is fixed

Hey folks, when exactly this shit will be fixed? I'm not renewing my annual subscription if it's not by EoY. There are so many small issues with the WP.com software that I don't know why I'm continuing paying you.

This was fixed on WordPress.com today by merging this fix.

The plugin will still need an update and a deploy.
