Client is not fetching missing messages

[dilshansdoq]

Describe the bug
Client (i.e. SDK) is not fetching messages which are missing. Take this example. A and B have p2p topic. Both have seen upto 50 seqid. A goes offline (or even left this p2p topic, just so A is not acknowledging B's messages). B sends 50 messages to A. A subscribes to topic and ask for data from server. get:what:data:since=50,limit=24. Server will send 24 messages from 100-76. A's view is full. Now A scrolls to see earlier messages. Range 75-51 is missing. SDK doesn't call server to fetch those messages.

To Reproduce
Steps to reproduce the behavior:

1. Login with two users A and B such that they are upto x seqid.
2. A goes offline. B sends 50 messages such that latest seqid is x+50.
3. A comes online. A will see latest n messages i.e. x+50-n to x+50.
4. A scrolls to see more messages. A cannot see x to x+50-n messages. These are missing

Expected behavior
No messages should be missing unless and until deleted from server.

Screenshots

Receiver(missing messages):

Environment (please complete the following information):

Console log
missing-messages.zip

Additional context
This gets solved, if A clears its cache. Now all messages are fetched with page size.
