It wont stop the spell unless you add a /stopcasting to the macro or you mash the key very fast and the first frostbolt hasn't fired yet.
You will just have to make sure you have enough , , to get the spell cast before you start casting it again. It should be ok it will depend on how fast you mash the key.

also if you want more than you could
/castsequence frostbolt , , , , frostbolt , frostbolt, frostbolt

/castsequence dot1,dot2,dot,3,dot4, , , , , , ,


so that it dots and casts frostbolt then just frostbolts add more , , spaces for timings
actually thos would work alot better with the following if you only want the mage to cast 1 spell.

Warlock:

/castsequence reset=target dot1,dot2,dot,3,dot4, and so on

Mage:

/cast frostbolt



no timing needed just spam the button
