Describe the bug / provide steps to reproduce it

A word (TODO) listed in the reject.txt file is being flagged as an error despite being surrounded by vale off and vale on comments in a Markdown file.

The issue appears to occur if the word appears on the same line as a bold or italicized word.

ex:

*Note*: <!-- vale off -->TODO<!-- vale on -->

This is also flagged:

**Note**: <!-- vale off -->TODO<!-- vale on -->

as are these:

_Note_: <!-- vale off -->TODO<!-- vale on -->
__Note__: <!-- vale off -->TODO<!-- vale on -->

However this works as expected:

Note: This works as expected <!-- vale off -->TODO<!-- vale on -->

Example output:

$ vale ./README.md

Possibly related to issues #340 & #878 however those were different enough that I decided to open an issue.
