RichTextBox link handling is broken

[RussKie]

• Have you experienced this same bug with .NET Framework?: No

Problem description:

RitchTextBox does not react to LinkClicked events at all.

Actual behavior:
Created two apps - .NET 4.6.1 and .NET Core side-by-side targeting msftedit.dll (not the old riched20.dll), loaded the same rtf:

Expected behavior:

.NET Core reacts to the events like .NET Fx did.

Minimal repro:

Move your initialization from constructor into load event then it works for me.

I think I'm starting to see a pattern here, with ComboBox (#1311) and ListView (#1607) not working when doing certain things in constructor initialization

Should be tested again once PR #1661 is in.
