 > This isn't actually an issue in the Customizer ''per se'' but rather in
 anywhere that core uses the Code Mirror library for editing.

 True, I completely forgot that Code Mirror is also in any other code
 editor like themes and plugins.
 After wasting a good time on #47692 for nothing, I was on autopilot on
 anything Customize.
 I am not sure why most Code Mirror issues have been associated to
 Component Customize (i.e. #44820)
 Wondering if there is a better component selection for this.
