Following the loss of the dielectric material, the capacitor will short circuit, and with sufficient short circuit current, the electrolyte will rapidly heat up and either leak or cause the capacitor to burst, often in a spectacularly dramatic fashion." Here "short circuit" is relative.
Otherwise, the reverse voltage may damage the overall capacitor with a bang or pop in a very short time (few seconds). This may lead to serious injury or hazardous fire (Tantalum capacitors do it happily). The aluminum layers in the electrolytic capacitor only bear the Forward DC Voltage (same as forward bias diode).
The vertical wire drawn next to the vertical capacitor shorts the two terminals of the capacitor. Any current flowing through this circuit segment will flow through the vertical wire and completely bypass the vertical capacitor due to the short. This means you can ignore the shorted capacitor -- it has no effect on the circuit.
Electrolytic capacitors can withstand for short instants a reverse voltage for a limited number of cycles. In detail, aluminum electrolytic capacitors with non-solid electrolyte can withstand a reverse voltage of about 1 V to 1.5 V. Solid tantalum capacitors can also withstand reverse voltages for short periods.
By having their shorted terminals, the voltage thereof is zero (more precisely, the potential difference between them), so that this element is not operational in the circuit, and can be removed for analysis. The other two capacitors are in series, hence that:
These guidelines apply for short excursion and should never be used to determine the maximum reverse voltage under which a capacitor can be used permanently. What you're talking about mostly happens in ac where for a short period of time a reverse voltage is applied and then a positive voltage immediately after that to reverse the small damage.
