It's actually not deleting itself, it's hiding it because all the other objects assigned to Style = Default were hidden.

I noticed recently that that behavior got accidentally broken at some point quite a while ago and I restored it in v5.

The concept is if all the objects currently assigned to the style are hidden or locked it makes the object you are assigning there to assume the same state.

If you hold down shift+ctrl when clicking the style swatch it won't change the object state.

Maybe since it was broken for a long time and nobody noticed it would be better to not do that. It's meant to make styles behave a little more similar to layers.
