Backticks in Code block produce nested <code> tags

[JasonHoffmann]

Description

If you try to add open and closing backticks inside of a "Code" block, then it produces a nested <code> block inside of it. The same is true of the Preformatted block

Step-by-step reproduction instructions

1. Create a new code block (or preformatted block)
2. Add text inside of two backticks
3. The text will be transformed into a <code> element, nested inside of the block

Expected behaviour

Backticks should retain their original formatting and not transform.

Actual behaviour

Backticks are converted into a <code> element
