You will need a Markdown Editor release later than 1.5.11 made after July 27, 2016 in order for spell checking to have the proper effect on all parts of the markdown file's content.
Changes in this release:
Added \U201E (double low-9 quotation mark) as a work break character.
Added support for spell checking markdown files within the Visual Studio text editor when using the Markdown Editor extension created by Mads Kristensen.
Updated the solution/project spell check to ignore certain pseudo-folders such as External Dependencies in C++ projects.
