GetPrinterAttributesAsync() throws "0 length attribute name found not in a 1setOf" from Lexmark printers

[xqrzd]

It seems to have regressed from this commit, 37b0660
Reverting to the prior implementation of GetNormalizedName() fixes the issue,

var normalizedName = string.IsNullOrEmpty(name) && prevAttribute != null ? prevAttribute.Name : name;
if (string.IsNullOrEmpty(normalizedName))
{
    throw new ArgumentException("0 length attribute name found not in a 1setOf");
}

When the exception is thrown in GetNormalizedName(), tag is Keyword, name is an empty string, and prevAttribute is two-sided-long-edge. If it's helpful I can attach the binary response from the printer.

@xqrzd Sorry, I missed notification.
If the tag is Keyword, the name is an empty string, and the prevAttribute is two-sided-long-edge, then why was return prevAttribute.Name; not used?
Is prevAttribute.Name also an empty string?
Even if you have 3 attributes with the same name then previous value should be calculated correctly.

I searched for public printers.
I tested GetPrinterAttributesAsync with:

• Lexmark X464de
• Lexmark M3150
• Lexmark MS510
• Lexmark T652

I didn't get an exception.
