exonum.MapProof.merkleRoot is inconsistent when the type of boolen in protobuf

[sfffaaa]

platform: Ubuntu 18.04
rust: rustc 1.38.0-nightly (78ca1bda3 2019-07-08)
exonum: 0.11-master
exonum-client: 0.16.4

Hi, there is a strange situation when I add boolean data in cryptocurrency.proto under cryptocurrency-advance (diff below). After adding this field, the exonum.MapProof cannot get the correct Merkle root from the javascript client.

Could someone help to check whether it is an issue?

The results are below.
From the backend side:

show entries [(PublicKey(cf0c5b2c...), Wallet { pub_key: PublicKey(cf0c5b2c...), name: "ababa", balance: 100, history_len: 1, history_hash: Hash(416e9a05...), test_fail: false })]
show missing_keys []
show merkle root Hash(b6cb148d...)

From the frontend side:

You can see the result of merkleRoot is different from "b6cb148d..." (backend result and tableRootHash in the frontend side) and "336bb671...". (walletProof merkleRoot in the frontend side).
