Describe the Bug

Using <code> tags in a header looks fine on the page but causes a problem in the sidebar navigation. Specifically, whitespace is lost.

Steps to Reproduce

Use markdown like <h5 id="bkmrk-why%C2%A0void%3F">Why <code>void</code>?</h5> in a page.
Save the page.

Example: https://resource.reworkflow.com/books/slate/page/birth-fields-on-custom-per-page#bkmrk-why%C2%A0void%3F

Expected Behaviour

Space between regular text and text should remain in the nav link.

Screenshots or Additional Context

Any space between regular text and text is lost in the nav link.

Thanks for reporting @WyattBest,
This has now been addressed in 77f125208e, to be part of the next patch release.

From what I could tell, this was unrelated to the use of <code>, but specific to handling   hence the update to the issue title.
