It didn't verify because SegWit (bech32 is native SegWit) has no standard for signing messages yet:
My doubt, regarding signing in segwit address is if this is a "bug" and will soon be corrected, or is it an abandoned feature?
It is neither a bug nor an abandoned feature. It is just that we are still working on creating a more generalized signing scheme that lets people sign with things like P2SH addresses (e.g. sign with a multisig address). There is simply no standard yet for signing with such scripts or with Segwit.
However,
if it's signed from Electrum, it can be verified from Electrum but only from Electrum because Electrum is using an own function to sign / verify here.
It verifies from Electrum:

And because of that it doesn't verify from Jochen Hoenicke website:
