Hiding properties in the built-in Link dialog

What I wanted to do was to hide the Title property in the built-in Link dialog.

When searching here on World I found several posts that talk about extending EpiLink with custom properties, such as:

• https://world.episerver.com/blogs/Anders-Hattestad/Dates/2015/2/extending-the-hyperlink-with-custom-field/
• https://world.episerver.com/forum/developer-forum/-Episerver-75-CMS/Thread-Container/2017/2/how-to-hide-some-properties-from-table-of-propertylistlttgt/
• https://github.com/mariajemaria/ExtendedEPiLink

But if I only need to hide a property, could this not be done using an EditorDescriptor instead of creating a custom dojo editor, overriding the LinkModel and all the rest?...

I was happy when I discovered that the answer is Yes :) 

I tried some variations of the below before finding the correct TargetType and way to get at the properties. This solution worked for me in a site that runs CMS 10.7:

    [EditorDescriptorRegistration(
        TargetType = typeof(LinkModel),
        EditorDescriptorBehavior = EditorDescriptorBehavior.ExtendBase)]
    public class EpiLinkEditorDescriptor : EditorDescriptor
    {
        public override void ModifyMetadata(ExtendedMetadata metadata, IEnumerable<Attribute> attributes)
        {
            base.ModifyMetadata(metadata, attributes);
            foreach (var prop in metadata.Properties)
            {
                if (prop.PropertyName == "Title")
                {
                    prop.ShowForEdit = false;
                }
            }
        }
    }

This hides the property both in the Link dialog that opens when adding a link in the TinyMCE editor and in the Link dialog used when adding a LinkItem (the same model is used in both cases).

If there is a better way of doing this, please let me know!
