Editor creates boxes around text when combining snippets with code

When using a snippet in your markdown file, followed by inline code, all text up until the code block get a box around the text.
This is not causing errors, but confuses and obstructs the experience.

See screenshots.



Reproduce the issue in the Adobe Markdown Authoring extension for Visual Studio Code using a markdown file with a snippet followed by inline code. Start by comparing the two attached screenshots with the rendered editor behavior; done means the unwanted box no longer surrounds the preceding text without introducing errors.
