That handbook is not telling the whole story.

Acetic acid (vinegar) forms acetates. Acetates are usually very water soluble, but also very unstable OUT OF SOLUTION and can easily come apart.

It’s true that the bond is poor OUT OF SOLUTION. But as long as there’s an abundance of acetic acid and it’s in solution, then it’s just fine. It’s only when it’s dried that it starts coming apart. At least that’s my understanding.
