Can we change this behavior?

If I key in an HTML link and make some mistake with it, such as forgetting a closing quote, then SF deletes the URL completely in the code, leaving not only a dead link but no way to recover the URL unless you remember what it was. That is, when you go to edit the post to fix the URL, you’ll see something like

[a]this link[/a]

in the code instead of something like

[a href=”http://somedomain.com]this link[/a]

On edit: Why do the “code” tags not work? Instead of showing the code as keyed, they allow it to be rendered!
