As far as I know, the grace period for edits is 5 minutes, and it doesn't matter if it's a normal or a suggested edit.

I proposed an edit for [this question](http://superuser.com/questions/684755/what-are-these-notches-on-the-side-of-the-pci-express-connector) and later on, well past the 5 minutes, I noticed I didn't correct a spelling mistake on the title.

Nonetheless, I clicked on *edit* and my suggestion summary was intact and I assumed that fixing the title wouldn't count as another suggestion. Is it right? Did I only propose one edit or was it two suggestions?
