Bug Report
A SocketException can occur when the ImageInline source is assigned to a link pointing to a picture on a remote server (a website). For example: UriSource ="https://docs.telerik.com/devtools/wpf/knowledge-base/images/kb-chartview-categorical-and-datetime-axis-0.png"
This could happen during the fetching of the image stream. In some cases, the server may give a NetworkStream or ConnectionStream, or similar Stream implementation, which keeps an open connection between the application and the server. If the connection get severed during the stream reading, an exception is thrown.
The exception message is: "Unable to read data from the transport connection: An existing connection was forcibly closed by the remote host."
The stacktrace is:

When trying to show the RadRichTextBox' LineNumberingDialog, nothing is displayed. This happens when using the NoXaml Telerik dlls and themes other than Windows11. The dialog is shown only in the Windows11 theme.
To work this around, add the following two lines in the App.xaml resources.

Using the SpreadStreamExport feature of RadGridView doesn't work as expected when exporting DateTime objects. It exports the dates as String values which prevents the date-related features (like formatting) to work in Excel.
To work this around, you can create a custom SpreadStreamExportRenderer and override its SetCellValue method. This will allow you to manually provide the DateTime object instead of the string.
public class MyRenderer : SpreadStreamExportRenderer
{
public override void SetCellValue(DataType dataType, object value)
{
DateTime date;
if (value != null && DateTime.TryParse(value.ToString(), out date))
{
base.SetCellValue(DataType.DateTime, date);
var cell = this.GetCell() as ICellExporter;
cell.SetFormat(new SpreadCellFormat() { NumberFormat = "yyyy-MM-dd HH:mm:ss" });
return;
}
base.SetCellValue(dataType, value);
}
} spreadStreamExport.RunExportAsync(FILENAME, new MyRenderer(), options);

NullReferenceException is thrown when the "var" CSS function is used in the HTML on HtmlFormatProvider Import method call.
The exception occurs only for CSS properties processed by RadRichTextBox. For example: "vertical-align", "font-family", "font-weight", "text-decoration-underline", etc.
The following HTML produces such error:
<span style="vertical-align: var(--my-variable);">
</span>
If the span tag doesn't have any content, the error doesn't occur.
The exception stacktrace is:

To work this around, avoid using the "var" function in the CSS.
