watchContractEvent doing requests with invalid block range

[Lopol2010]

Check existing issues

• I checked there isn't already an issue for the bug I encountered.

Viem Version

2.16.1

Current Behavior

When listening events via watchContractEvent, console is filled with error:
RPC Request failed:
code: -32000, message: invalid block range params

Request body: "method":"eth_getLogs" ..."fromBlock":"0x2649c99" ... "toBlock":"0x2649c97"

As you can see fromBlock is greater than toBlock.
I assume bug appears in these lines:

viem/src/actions/public/watchContractEvent.ts

Lines 242 to 243 in f7afaa2

	fromBlock: previousBlockNumber + 1n,
	toBlock: blockNumber,

Expected Behavior

The case with invalid block range should be handled by watchContractEvent function, so that it won't make request with invalid block range.

Steps To Reproduce

Listen for BSC mainnet contract events via RPC node https://rpc.ankr.com/bsc
And these arguments:

    let unwatch = client.watchContractEvent({
        abi: ...,
        address: ...,
        pollingInterval: 4000,
        eventName: ...,
        onError: err => { console.log("[Listener] error:", err); },
        onLogs: logs => {
        }
    })

Hmm, must be some load balancing issue on the RPC Provider side. Will add a guard to fix.
