Description

Steps to reproduce:

Go to New Issue page
Fill in a title, and for content, fill in both YAML front matter and a task list, such as the below:

---
foo: bar
---
- [ ] checkbox

Click "Create Issue"
Once the issue is created, a checkbox is rendered. Click the checkbox to make it checked.
Reload the page

I expected the checkbox to be checked and all other text including front matter to be the same as was originally entered.

Instead, a seemingly random character in the middle of the front matter or other markdown text content, depending on character positions, is replaced by an x character. Unchecking will replace the character with a space character. The problem has also been observed in pull request descriptions.
