It was similar with Phoenix "close wallet" button.
If they send it really low fee, you can always bump it via Child-Pays-for-Parent (CPFP) from the receiving wallet.
This is just spending the unconfirmed utxo using a higher fee rate to incentivize miners to include both - they want your higher fee but need to process the small fee first
That's exactly what I was going to say... Since something similar happened to me with Phoenix when I went to close my wallet... thank goodness you're publishing it so that we can all be warned...
