Can't parse Option<'T> from a json field that's either missing or null

[pkese]

What's the required set of options that gets the following code to work?

Either I'm getting: Missing field for record type
or The JSON value could not be converted to System.Double. Cannot get the value of a token type 'Null' as a number.

#r "nuget: FSharp.SystemTextJson, 1.2.42"
open System.Text.Json
open System.Text.Json.Serialization

let options =
    JsonFSharpOptions.Default()
        // Add any .WithXXX() calls here to customize the format
        .WithSkippableOptionFields()
        .WithAllowNullFields()
        //.WithUnwrapOption()
        .ToJsonSerializerOptions()

type Doc = { x: float option }

let json = """
    [
        {"x": 1.0},
        {"x": 2},
        {"x": null},
        {}
    ]
"""

JsonSerializer.Deserialize<Doc[]>(json, options)
|> printfn "%A"

Note: The above example is just a minimal reproduction that I extracted from a real world sample,
i.e. I'm dealing with a REST API, that returns some properties as nulls while other properties get omitted from response.

This is released in v1.3.13:

JsonFSharpOptions.Default()
    .WithSkippableOptionFields(SkippableOptionFields.Always, deserializeNullAsNone = true)

Thank you @Tarmil.
I highly appreciate your effort.
