It is resolved in 0.19.0 by downgrading the bundled bitcoin canister.

> I assume that this is the reason the Bitcoin canister was downgraded in this release, but might be useful to make this explicit. That’s correct. We downgraded the bundled bitcoin integration canister in dfx v0.19.0 to address the linked issue.

The actual fix on the bitcoin canister side was merged: [fix (EXC-1590): make burning cycles configurable by ielashi · Pull Request #286 · dfinity/bitcoin-canister · GitHub](https://github.com/dfinity/bitcoin-canister/pull/286).

We are waiting for a new release of the bitcoin canister so that we can include it in `dfx`.
