Dotliquid Ignored CultureInfo settings if CultureInfo.CurrentCulture is InvariantCulture

[heggi]

Dotliquid version

2.2.692

Expected behavior

Correct format dates via date filter

Actual behavior

Date format ignored, dates format as invariant full date

Steps to reproduce the Problem (you can add files)

CultureInfo.CurrentCulture = CultureInfo.InvariantCulture;

var rendered = DotLiquid.Template
    .Parse("{% param culture='fr-FR'%} {{ MyDate | date: \"dd.MMMM.yyyy\" }}")
    .Render(DotLiquid.Hash.FromAnonymousObject(new
    {
        MyDate = DateTimeOffset.UtcNow,
    }));

Console.WriteLine(rendered);

rendered value must be 01.décembre.2023, but i got 11/30/2023 22:16:48 +00:00

If comment out CultureInfo.CurrentCulture = CultureInfo.InvariantCulture; or replace CurrentCulture via any other Culture (for example en-gb), code works fine.

Next code don't work as expected too

CultureInfo.CurrentCulture = CultureInfo.InvariantCulture;

var rendered = DotLiquid.Template
    .Parse("{{ MyDate | date: \"dd.MMMM.yyyy\" }}")
    .Render(DotLiquid.Hash.FromAnonymousObject(new
    {
        MyDate = DateTimeOffset.UtcNow,
    }), CultureInfo.GetCultureInfo("fr-FR"));

Console.WriteLine(rendered);

It seems like the filter is not working, such as using C# syntax. Did you try uppercase Date? In both invariant culture and French, dot separators are the same. Here is a test case proving this working correctly:

[Test]
public void TestCultureDate()
{
    var Dec0123 = new DateTime(2023, 12, 1);
    using (CultureHelper.SetCulture("en-US")) // Pre-select a thread culture for Before value (jp-JP)
    {
        Helper.AssertTemplateResult(
            expected: "01.décembre.2023",
            template: "{% param culture=cultureValue%}{{ MyDate | date: \"dd.MMMM.yyyy\"}}",
            localVariables: Hash.FromAnonymousObject(new { MyDate = Dec0123, cultureValue = "fr-FR" })
        );

        Helper.AssertTemplateResult(
            expected: "01.December.2023",
            template: "{% param culture=cultureValue%}{{ MyDate | date: \"dd.MMMM.yyyy\"}}",
            localVariables: Hash.FromAnonymousObject(new { MyDate = Dec0123, cultureValue = "" }) // ""=InvariantCulture
        );
    }

    using (CultureHelper.SetCulture("")) // Pre-select an invariant culture
    {
        Helper.AssertTemplateResult(
            expected: "01.décembre.2023",
            template: "{% param culture=cultureValue%}{{ MyDate | date: \"dd.MMMM.yyyy\"}}",
            localVariables: Hash.FromAnonymousObject(new { MyDate = Dec0123, cultureValue = "fr-FR" })
        );
    }
}
