Wiki: Non-markdown files with a file extension starting with .md* are shown as wiki pages
All files ending with .md* are shown as wiki pages.
This includes files with a longer file extension then only .md such as .mdata.
If such a file is attached to a wiki entry, it is automatically added as a separate wiki entry and can be opened by browsing through the wiki pages.
Steps to reproduce
Create a test file and save with any file extension starting with .md, e.g. .mdata or .mdumb and attach this file to a wiki entry such as this:
What is the current bug behavior?
The test file is shown as a wiki page.
What is the expected correct behavior?
Files with a file extension other then .md should not be shown as markdown wiki pages.
Only search for explicit .md file extensions.
