Web 2.0 : WebToolbarFlexibleSpace is not recognized by the compiler

it is in the documentation : https://documentation.xojo.com/api/user_interface/web/webtoolbar.htmlFlexibleSpace
but if I write :

Me.AddItem( New WebToolbarFlexibleSpace)

I get an error :

WebPageMain.ToolbarMainTop.Shown, line 1
Can't find a type with this name
Me.AddItem( New WebToolbarFlexibleSpace)

Sorry. Just create a WebToolbarButton and set its Style property to WebToolbar.ButtonStyles.FlexibleSpace

I’ll file a report internally.
