Inserting ` and pressing right arrow deletes text

[axelsparr]

Describe the current behavior
A clear and concise explanation of what is currently happening.

When a ` character is typed and right arrow key is pressed another ` is inserted removing the adjacent character. This doesn't happen if ` is copy pasted. It's present both inside and outside of comments. In code cells if no other character is next to the ` it creates a new line and a new `. It's present both in code and markdown cells but in markdown cells it doesn't add another ` unless there is a character already next to the initial `.

Describe the expected behavior
For the cursor to simply move without removing text.
