Link titles are removed

[susnux]

Describe the bug
If a markdown file includes a link with a title set, the title is either removed or set to the link target.
As the text app does not use the title (within the editor the author name overlays the link title so the title is never shown),
there is no reason to change it in the source.

e.g. if you are using the markdown file also in other applications it changes its behavior.

To Reproduce
Open a markdown file containing

[Dashboard](/apps/dashboard "To the dashboard")

Save and open the markdown file with a text editor, the link now looks like this:

[Dashboard](/apps/dashboard)
