Issue #456 revealed some strange behaviour that is normally masked by the use of the Sanitizer plugin (hence the addition of a test page that is minimal in terms of plugins). This turned out to be because we were wrapping text nodes that had no content.
To fix the issue these nodes are currently ignore in the wrapping process but it would probably be better to delete them from the content.
Testing
The easiest way I've found to have this be repeatable is to change the default content to contain some indented paragraphs. If you then bold any word in the content all the whitespace becomes wrapped in a paragraph creating noticeable changes to the visual spacing.
