SelectSingleNode() doesn't select <tr>

[ashahabov]

In the provided code snippet, the SelectSingleNode() method is expected to return an instance of INode for the selected <tr> element within the HTML content. However, the method is returning null, which indicates a potential bug in the library.

Repro

var context = BrowsingContext.New(Configuration.Default);
var parser = context.GetService<IHtmlParser>();
var document = await parser.ParseDocumentAsync("<table><tr></tr></table>");

var trNode = document.Body.SelectSingleNode("//table/tr");

Actual Result

trNode is null

Expected Result

trNode is not null
