When I put a link into a post, I like to click it when pre-viewing -- I've been known to put the wrong one in and want to catch it. I-Hub appears to parse the link (and add colours) so even if it's OK, it chokes during a preview click.
I must check links after posting and make changes in the 15 minute window.
When I clicked the Edit button, the I-hub window truncated my post near the beginning of the link.

Was all that was left of the link.
NEW STUFF HERE...
During my attempts to post my earlier message, clicking EDIT would not only remove pieces of my post, it would ADD a bit too. The target="_new">http.... stuff wasn't there previously.
