How common is it for journal to reject a solicited paper?

A guest editor at a peer-reviewed academic journal solicited me to write a paper. I initially hesitated for lack of time. But the editor's invitation was courteous. So I sent an abstract, which was accepted by the editor.

I submitted the 6k-word paper a few weeks later, taking care to comply to the submission guidelines (I downloaded the journal's CSL file for bibliographic references, for example).

I just received a rejection letter. I know an invitation is not a ticket to bypass the reviewers. Still, I am rather stunned. I'll get over it, but I was wondering how common it is for academic journals to reject solicited papers?
