Given a self-closing tag such as <input type='text' />, doing a ToHtml() on it, or using the OuterHtml property both return an unclosed tag.

Steps to Reproduce

var config = Configuration.Default;
var context= BrowsingContext.New(config);
var source = "<input type='text' />";
var document = await context.OpenAsync(req => req.Content(source));
var input = document.QuerySelector("input");

Expected behavior: returns <input type='text' />

Actual behavior: returns <input type='text'>

Environment details: Windows, .NET 6.0.14

Possible Solution

I believe the above line needs to have a code path that adds /> when selfClosing is true.
