it is thrown by AxIWebBrowser2.Refresh();
and also catched.
Anything to worry about?

public override void Refresh()
{
try
{
if (ShouldSerializeDocumentText())
{
string text = DocumentText;
AxIWebBrowser2.Refresh();
DocumentText = text;
}
else
{
AxIWebBrowser2.Refresh();
}
}
catch (Exception ex) when (!ClientUtils.IsCriticalException(ex))
{
}
}
