ord wallet resume waits for the etchings in alphabetical order. If you have pending etchings for RUNE.A and RUNE.B, and the commit for RUNE A is unconfirmed while the commit for RUNE.B has 6 confirmations, wallet resume will wait for the RUNE.A commit to have 6 confirmations before sending the reveal for RUNE.B.

It would be better if it waited for all of them independently, because if we have 2 etchings with 0 confirmations we don't know which one will get to 6 confirmations first.
