This is because this code explicitly checks whether the data argument to display.Markdown is an existing path, and if so, reads that path instead of displaying the text itself.
This also leads to a weird side effects, allowing to display the files one may not intend to display:
Is it a good idea to decide whether to read a file or to display the text depending on whether the text resolves to an existing path? Perhaps this should be done with a flag instead, i.e. if the user explicitly passes filename=?
