Looks like it finally got confirmed... + 1,854 minutes later... that is nearly 31 hours...
and it was in a block mined by ViaBTC so I assume the TX Accelerator helped
Next time, don't use such a low fee, or enable the "Replace By Fee" (RBF) option in Electrum... or investigate "Child Pays For Parent" (CPFP)... that will give you a couple of extra options to help push stuck transactions along.
