 I noticed that the customizer.js file in the Twenty Twenty theme is
 loading in the customizer no matter if the theme is being edited or if a
 plugin is using the customizer. When using any plugin that takes advantage
 of the customizer you will see the attached type error.

 Offending Code:
 {{{
 api.control( 'accent_hue_active' )
 }}}

 Uncaught TypeError: Cannot read property 'setting' of undefined. That's
 because plugins are loading their settings.

 So far I've seen this cause issues with the jQuery UI Slider controls,
 they just won't load. Switching back to the TwentyNineteen theme or
 TwentySeventeen theme resolved the issue.

 Adding a try catch block around this twenty twenty setting specific code
 solves the problem for me. Try catch is fully supported now so I think
 this could be a great, minimal code, solution to this bug.
