I'll add another case that might be affected by the same bug:
Transactions failed in Polkado Asset Hub: https://assethub-polkadot.subscan.io/xcm_message/polkadot-57b7063a03798764c36226132fae6145f7b150b4
The account sent USDC from Acala to PHA using the Acala bridge. No issues: https://acala.subscan.io/extrinsic/5876246-2
Polkadot Relay Chain processed the message: https://polkadot.subscan.io/extrinsic/20146096-1?event=20146096-3
Polkadot Asset Hub generated the event xcmpqueue (Fail)
:
https://assethub-polkadot.subscan.io/extrinsic/5971079-0?event=5971079-1
I don't see any "trapped" balance. The sender account had enough to pay for the fees in ACA, and some DOT (0.016 DOT) were transferred to pay for the destination fee.
According to Joe, 0.016 DOT were not enough and the balance dropped below the ED.
Is there an existing issue?

Description of bug
The XCM extrinxic 6353817-2 in Kusama Asset Hub resulted in an
Attempted
FailedToTransactAsset
error because the account tried to transfer all transferable funds.Due to the limitations of the new delivery fees manager, the funds should have been trapped but were instead just withdrawn.

This could impact the total issuance.
