Shortcuts not working in Pre or Post Element Text Apex 22.1

Latest document clearly states that Shortcuts can be used here but they dont seem to have any effect.

17.6.1 What is a Shortcut?

Use a shortcut to define frequently used code once and then reference it in many places thus reducing code redundancy. For example, you can create a shortcut to define a page control such as a button, HTML text, a PL/SQL procedure, or HTML.

You can use a shortcut within the following locations:

• The Region Source attribute of regions defined as HTML Text (with shortcuts).
• Region Header and Footer Text attribute.
• Item Label attributes, Pre Element Text, Post Element Text
