Having inline code in chapter title outputs additional strange text in top left corner

Describe the bug I’m currently running 0.7.0b. I have a chapter in Zero 2 Data 8 called “The datascience Package” (link). Having inline code in the chapter title causes this strange text to appear on the page (see below).

To Reproduce Steps to reproduce the behavior:

1. Changing the working directory to root zero-to-data-8
2. Running jupyter-book build .
3. Looking at the file locally.

Expected behavior Building should not have the upper left text to show up.

Link to book repository: https://github.com/data-8/zero-to-data-8

Environment (please complete the following information):

• Python Version 3.7
• Output of jupyter-book --version: 0.7.0b

have a fix for this in the SBT here: https://github.com/executablebooks/sphinx-book-theme/pull/126...I’m still not sure if this is a bug in the parser though

Alright I figured out where the issue is, but I’m thinking this could be myst-parser bug or it could be expected Sphinx behavior.

Right here, we set the title of the page: https://github.com/executablebooks/sphinx-book-theme/blob/master/sphinx_book_theme/layout.html#L17

but if there is formatting in a title, then the HTML for the title gets included in the title variable:

E.g. if I make the theme title The `Sphinx Book` theme, then title equals:

'The <code class="docutils literal notranslate"><span class="pre">Sphinx</span> <span class="pre">Book</span></code> Theme'

This is causing the second half of the title to spill out into the page body
