In Scratch 2 the workaround for non existing

stop sound [ v]::sound

block was to create a clone, play sound which needed to be stopped and immediately delete the clone which resulted in stopping only that sound.
Doing that in Scratch 3 instead of stopping the sound, will put it into a glitched state in which it can't be stopped by stopping the project or using one of those blocks:

stop all sounds
stop [all v]

I know other ways of stopping specific sound, but it would be nice to have this glitch fixed.
