Lightning channel stuck while opening due to low fee

I'm using Electrum from master branch. I tried to open a new channel to a node and set the fee manually using the static method. Looks like it wasn't enough because I've got this in the log (there were no GUI error messages and no transactions appeared at the history tab):

I | transaction | adding signature for <nodeid>
D | transaction | is_complete True

Your transaction is trying to replace another one in the mempool but it does not meet the rules to do so. Try to increase the fee.

I don't see the funding transaction in the history and it clearly hasn't been broadcasted (this txid isn't found on any block explorers). The channel now is stuck in REESTABLISHING peer state, I tried to force close it (unsuccessfully, because there's no funding tx). My balance is unchanged so the only problem is this stuck channel that I can't remove. lnd has abandonchannel command that I believe does exactly what I want, just remove it no questions asked... but I can't find anything like that in the Electrum console or GUI.

Start by reproducing the low-fee channel-opening failure from the reported log and inspect how Electrum handles the channel's REESTABLISHING state. Review the Electrum console and GUI entry points related to channel management, using lnd's abandonchannel behavior as the requested reference. Done means a channel with no broadcast funding transaction can be removed cleanly.
