I found it quite funny that the heat-shrink around the fuse inflated and contained all the metal vapor and made the short worse.
It was not such a good thing to "tart up" a cheap Chinese power supply for sale in a UK high street store like that.
The original Chinese units have less of this extra insulation in them and better air flow to keep them cool.
Those safety people often get it wrong or put the manufacturer under pressure to get it wrong.
The replacement was an original Chinese unit from Hong Kong and still works fine even though the mains lead was dreadful.
