+		 *
+		 * Will produce this on backspace:

+		 *

+		 *
+		 * This fixes the following delete scenarios:
+		 *  1. Delete by pressing backspace key.
+		 *  2. Delete by pressing delete key.
+		 *  3. Delete by pressing backspace key with ctrl/cmd (Word delete).
+		 *  4. Delete by pressing delete key with ctrl/cmd (Word delete).
+		 *  5. Delete by drag/dropping contents inside the editor.
+		 *  6. Delete by using Cut Ctrl+X/Cmd+X.
+		 *  7. Delete by selecting contents and writing a character.
+		 *
+		 * This code is a ugly hack since writing full custom delete logic for just this bug
+		 * fix seemed like a huge task. I hope we can remove this before the year 2030.
