It is partially the tank's fault because although you didn't catch up and heal them, they ran ahead knowing that you were new, so as a tank they should be prepared survive on their own for long enough for a new player to catch up, or alternatively go slower.
As I explained previously, it's almost always someone's first time, so if you want to "pull big" as a tank, you have to learn how to make it easy for a new player to heal you and most tanks you meet won't have enough tanking experience to do that, so they cause a wipe in certain dungeons.
To catch up with them, what you can do is press P, go to General and drag the Sprint action onto your hotbar. Then you can keybind the hotbar slot to a key (I use R). If you look in the party list, you can see when the tank uses Sprint with the dash symbol and use it yourself to keep up with them. It lasts twice as long if you use it when not fighting, so try to use it before attacking or healing rather than after.
The best mindset to have in a dungeon is that it's not any one person's fault that there was a wipe. Every single person including the DPS should ask themselves "what could I have done to prevent it?"
