## HtmlTextWriter does not render `<br/>` element correctly

### Scope
Edge

### Version Introduced
4.6

### Source Analyzer Status
Available

### Change Description

Beginning in the .NET Framework 4.6, calling
<xref:System.Web.UI.HtmlTextWriter.RenderBeginTag(System.String)>
and
<xref:System.Web.UI.HtmlTextWriter.RenderEndTag>
with a `<BR />` element will correctly insert only one `<BR />` (instead of two)

- [x] Quirked
- [ ] Build-time break

### Recommended Action

If an app depended on the extra `<BR />` tag,
<xref:System.Web.UI.HtmlTextWriter.RenderBeginTag(System.String)>
should be called a second time. Note that this behavior change only affects apps
that target the .NET Framework 4.6 or later, so another option is to target a
previous version of the .NET Framework in order to get the old behavior.

### Affected APIs
* `M:System.Web.UI.HtmlTextWriter.RenderBeginTag(System.String)`
* `M:System.Web.UI.HtmlTextWriter.RenderBeginTag(System.Web.UI.HtmlTextWriterTag)`
