Intention behind "EventHandler" in CA1711 ?

I first posted in the wrong repo: https://github.com/dotnet/docs/issues/53193
therefore, I post again here.

I have created a class named EventHandler, which IMHO does not require more text in its name, since it is a nested class inside another class with meaningful name.

The analyzer now complains about the name (CA1711). What is the reason for having "EventHandler" in CA1711? I guess dozens, if not hundrets of classes in .NET carry the text "EventHandler" as part of their name, so these violate that rule, e.g.:

ContextMenuEventHandler
InitializingNewItemEventHandler
TextChangedEventHandler
ToolTipEventHandler

(from System.Windows.Controls)

... (many!)
