Calling any of the on.* methods with a quotation from the server-side causes the following exception:

The type initializer for '.$Attr' threw an exception. ---> WebSharper.JavaScript.ClientSideOnly: This function is intended for client-side use only. 
at WebSharper.UI.Next.Client.Attr.OnAfterRender(FSharpFunc`2 callback) 
at .$Attr..cctor() --- End of inner exception stack trace --- 
at .$`1 acc, Address a) 
at .$Attr.func@103.Invoke(Info meta) 
at WebSharper.UI.Next.Attr.Write(Info meta, HtmlTextWriter w, Boolean removeDataHole) 
at .$Doc.Write@131-2.Invoke(Attr a) 
at Microsoft.FSharp.Primitives.Basics.List.iter[T](FSharpFunc`2 f, FSharpList`1 x) 
at WebSharper.UI.Next.Elt.Write(Info meta, HtmlTextWriter w, FSharpOption`1 res) 
at WebSharper.Sitelets.Content.renderBody@164.Invoke(HtmlTextWriter tw) 
at .$Page.get_Default@43.Invoke(FSharpOption`1 doctype, FSharpOption`1 title, FSharpFunc`2 writeHead, FSharpFunc`2 writeBody, HtmlTextWriter writer) 
at WebSharper.Sitelets.Content.writeBody@157.Invoke(Stream stream) 
at WebSharper.Owin.Internal.W2O.WriteResponse@164.Invoke(Task`1 obj)

This is caused by Attr.ValidateForm, which contains client-side functionality, being a top-level binding instead of a function so it gets called when the module is referenced.
