Electrum is not affected by that, it's a bug in the bitcore library used by Copay.
Even if you can use BIP39 seeds in Electrum, we do not recommend to do so.
It is safer to create an Electrum seed. For explanation see
http://docs.electrum.org/en/latest/seedphrase.htmlso if i use a seed generated by electrum itself. even if i moved devices several times and resync the wallet on the new device. no problem.. correct?
