My immediate thought was that static friction was keeping it up. Cohesion/adhesion being a factor would come later.
How did I come up with that idea immediately? Well… because “A block is stationary on a ramp because of friction, now do some math about the situation...” is a central intro physics problem. And, it’s how I keep my pen from falling when I hold it. Now, you can have something tip without friction being enough to stop it (because there’s not much rubbing against the wall or support), but it does get you in the general space of “those clingy forces”.
