LINQPad v. 8.3.7: Unable to export IAsyncEnumerable to Excel

Sample code:

async Task Main()
{
    RangeAsync(10, 3).Dump();
}

static async IAsyncEnumerable<int> RangeAsync(int start, int count)
{
    for (int i = 0; i < count; i++)
    {
        await Task.Delay(i);
        yield return start + i;
    }
}

It is not possible to export the table.
Even when choosing Export -> To Excel via .XLSX (all tables), LINQPad just says "No tables to export."
The only way to export to Excel is via HTML.

Would it be possible to fix this?
