Capacitor burst or is it just glue?

I once took a photo of the capacitor:

The capacitor is on a laptop mainboard.

It's glue.

Capacitors usually do not bulge sideways, but horizontally

Is glue so that it does not slip during wave soldering

I tap glue.

A broken capacitor looks different.

It looks broken.

No he does not.

But he does, and I don't mean the glue.

No, he still doesn't
