I'm currently having the following issue:

I'm using Humanizer in a razor component running in a WebAssembly Blazor project. My component has a class Localizer which provides a CultureInfo. When passing a DateTime through the Humanizer, I always get the English result. Here's the code snippet:

<small class="pr-2">
    <abbr title="@item.Date.ToString(Localizer.GetCulture())">
        @item.Date.Humanize(culture: Localizer.GetCulture())
    </abbr>
</small>

The Localizer is not the problem, as the Date format in the tooltip is correctly changed when I change the culture:

Culture en-US:

Culture de-DE:

Some additional information:
The same issue happens with TimeSpan, but non time related functions seem unaffected e.g. 5.ToWords(culture: Localizer.GetCulture()) works just as expected.

Upon further analysis, the problem seems to occur while loading the resource string:

The culture has been correctly passed down, but loading the resource always returns the english string.
