Attached has a one byte overlap between 1st and 2nd data segment from client at
sequence #5.

When viewed in the bottom pane it shows "Reassembled TCP (411 bytes)" and the
start of the request is "GET /test-cgi?* HTTP/1.1"  which is incorrect.

When viewed by following the stream, it shows "Entire conversation (410 bytes)"
and the start of the request is "GET /est-cgi?* HTTP/1.1", which is correct.
