Proxy.proxy is marked as nesting supported, but not working on-device

[rossbulat]

When I attempt to sign a staking.bondExtra extrinsic using Ledger as an Any proxy, I am getting the following error:

Error: Call nesting not supported

To describe the call structure further, here is the method value of the transaction:

{
    "method": {
        "args": {
            "real": {
                "Id": "1hYiMW8KSfUYChzCQSPGXvMSyKVqmyvMXqohjKr3oU5PCXF"
            },
            "force_proxy_type": null,
            "call": {
                "args": {
                    "max_additional": "53,987,518,958"
                },
                "method": "bondExtra",
                "section": "staking"
            }
        },
        "method": "proxy",
        "section": "proxy"
    }
}

Was proxy.proxy mistakenly marked as Nested supported?
