Describe the bug

I believe I'm hitting a discrepancy between geth and anvil in receipt root calculation:

ERROR[06-05|14:42:17.255] sequencer temporarily failed to start building new block err=
 "temp: failed to fetch L1 block info and receipts: failed to fetch list of receipts:
   expected receipt root 0x987c20331e3e9b054da27a8269e5e558c0db18344de1a8413d0eaec32d63884d but computed 0x6a3f473ade72ee4cb1d10a27d4cae4e2bbcdc3394e94de33c3f76654568ecf85 from retrieved receipts"

This issue resembles #7698, which was fixed in #7718.

See

foundry/crates/anvil/src/eth/backend/executor.rs

Line 204 in 00854b6

let receipts_root = trie::ordered_trie_root(receipts.iter().map(alloy_rlp::encode));

As far as I can tell, this is the only place in anvil where receipts_root is calculated, and it uses the same rlp::encode function that was replaced in the above fix for the transaction root.

Drive-by request: Out of necessity, I'm currently using a build from the open PR #7918, which was approved with CI failures, but now seems stagnant. Can it be merged?
