trace_filter in Parity Trace nodes sometimes fails to detect transactions in new blocks

[AlexWilton]

Before filing a new issue, please provide the following information.

• Parity Ethereum version: 2.2.7 / 2.3.0
• Operating system: Linux (Debian in Docker on CentOS 7)
• Installation: downloaded from releases, built into container (debian)
• Fully synchronized: yes
• Network: ethereum
• Restarted: yes

Your issue description goes here below. Try to include actual vs. expected behavior and steps to reproduce the issue.

When making json-rpc calls to method "trace_filter" (https://wiki.parity.io/JSONRPC-trace-module#trace_filter), providing:

• fromBlock
• toBlock (using most recent block height retrieved from tracing node),
• toAddress
• fromAddress

Sometimes (<10% time) an empty array of traces is returned, despite seeing transactions confirmed within block range on etherscan. However, if I were to make exact same call later (say 30 seconds), i would see the transaction appear in the returned trace.

Is there some sort of delay before being able to tracing brand new blocks?
