Re: Re: Build error with The name `enable_javascript_markup' does not exist in the context of `WebKit.Settings?' when trying to build for buster-backports

The compilation error happens because the symbol `enable_javascript_markup`
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

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;
}
