Would this tiny tear in top be of any concern?

[patssle]

My top is in perfect condition except this one tiny spot. And I'm trying to decide if I want to just sew in a new rear window. Has anybody experienced a small tear like this - can I expect it to stay this way or is this just the beginning of it being to unravel and unstitch itself? If it's going to snowball then I should buy a new top...but that's a significant price difference!
