The compilation error happens because the symbol

property isn't present in vala vapi files, which means that 
valac-vapi has to be
updated, currently the version in buster is 0.42. For a grep of 
`enable_javascript`,
I get the following:

$ grep enable_javascript /usr/share/vala-0.42/vapi/webkit2gtk-4.0.vapi
                public bool get_enable_javascript ();
                public void set_enable_javascript (bool enabled);
                public bool enable_javascript { get; set construct; }

And for the same, with vala 0.46 on testing:

$ grep enable_javascript /usr/share/vala-0.46/vapi/webkit2gtk-4.0.vapi
                public bool get_enable_javascript ();
                public bool get_enable_javascript_markup ();
                public void set_enable_javascript (bool enabled);
                public void set_enable_javascript_markup (bool enabled);
                public bool enable_javascript { get; set construct; }
                public bool enable_javascript_markup { get; set construct; }


Which means that the symbol isn't currently present in the 
valac-0.42-vapi

I'm not so familiar with gtk/vala, but quite comfortable with 
backporting.

I can backport vala, but isn't having to use a new vala version to use 
a new webkitgtk a design bug? Can't we include vala bindings of 
webkitgtk in a separate package or part of webkitgtk? Or is webkitgtk 
considered part of vala itself?

A minimal vala example for testing:

using WebKit;

// valac --pkg webkit2gtk-4.0 --thread test.vala
public static int main (string[] args) {

  var test = new WebKit.Settings();
  test.enable_javascript = true;
  test.enable_javascript_markup = true;
  return 0;
}
