Longer Valid Chain Data Replacement Issue on blockchain demo website.

[anurag-y]

When a longer valid chain is created which differs from other smaller chains, the data of the longer chain is not replacing the data of shorter chains (though, the hashes are replaced).
Suppose 3 peers have 5 blocks, all in sync and then another peer joins and creates 7 blocks with blocks different from other peers. Here the longer valid blockchain should replace the smaller blockchains. But only the hashes are replaced, and the data remains the same. Only new blocks 6th and 7th get added to all other peers' blockchains. Their 1-5 blocks contain the same data (Hashes are replaced by those from the longer valid chains).
