In the capacitor situation, the reason the liquid doesn't start flowing out of the capacitor horizontally is analogous. Consider a small volume element of the liquid somewhere near the edge of the capacitor, which experiences the pressure differential pushing it outward. That outward force is compensated by a certain inward force.
I hope that it was not mercury! The capacitor is of a cylindric shape with two wires at bottom, about 7mm in diameter. It's the electrolyte. As far as I know there is no mercury involved. On wikipedia en.wikipedia.org/wiki/Electrolytic_capacitor you can find what are the most used electrolytes.
Voltage Rating: If a capacitor cannot handle the voltage applied to it, it may fail prematurely. This is often due to selecting a capacitor with a voltage rating too close to the operating voltage. Current Capacity: Similarly, capacitors have a maximum current capacity. Exceeding this capacity can lead to overheating and failure.
Capacitor failure is a significant concern in electronics, as these components play a critical role in the functionality and longevity of electronic circuits. Understanding the nuances of capacitor failure is essential for diagnosing issues in electronic devices and implementing effective solutions.
Voltage Surges: Exposure to voltage levels exceeding the capacitor’s rating can lead to the breakdown of the dielectric material, failing. These surges can be sudden and unexpected, often from power spikes or lightning strikes.
Identification: Electrolytic capacitors can leak their internal electrolyte when they fail. This leakage can appear as a wet or crusty residue around the base of the capacitor or seeping from the top. Consequences: The leaked electrolyte can be corrosive and may damage the circuit board or other components it comes into contact with.

Electrolytic capacitor
An electrolytic capacitor is a polarized capacitor whose anode or positive plate is made of a metal that forms an insulating oxide layer through anodization.This oxide layer acts as the dielectric of the capacitor. A solid, liquid, or gel electrolyte covers the surface of this oxide layer, serving as the cathode or negative plate of the capacitor.
