Is this common? It's getting annoying...

Unfortunately, this is fairly common, at least with a lot of low level dungeons. One thing that you may consider, at least in my experience while leveling, is that healing in general if completely overpowered at that level, to be able to deal with potential issues like this. It may be a good time getting practice in pulling a bit faster, and more fluidly. at level 50, speed pulling is all people do, so starting practicing early is amazing.

My unofficial goal in a dungeon is to make sure that the healer at no point ever feels bored while running through the dungeon. when I see a SCH especially, I will start the dungeon with saying "we're gonna have some fun, heals!" in party chat, and then after the initial buffs, I'm off pulling 1-2 groups like no tomorrow, and pulling the next groups before the last mobs die. It earns the healers commendation almost every time.

I'm 95% sure that if you are pulling at a respectable speed, the dps aren't running in front of you either. they are too busy killing the last mobs you hit, while you are running for the next set.

Its great to be the one setting the pace, but the pace has to be set at the pace that is optimal for what the group can handle. if you go too fast, you wipe. you go too slow, the dps get bored and start pulling for you. Determining what a group can handle is the other half of the job.
