This is just a test, if inserting a link https://code.ros.org/trac/ros-pkg/ticket/424242" title="inexistent ticket page title">like this via the link button does work, as I had been experiencing difficulties with that. No brackets involved..
edit: gotcha!
What I wrote in my answer, plain markdown:
[like this](http://https://code.ros.org/trac/ros-pkg/ticket/424242 "inexistent ticket page title")
What the preview looks like (all linked and blue):
like this
What the answer looks like afterwards:
https://code.ros.org/trac/ros-pkg/ticket/424242" title="inexistent ticket page title">like this
Anyone else?
As in the edit window it looks like before, there seems to be a disturbing parser when displaying posts..
