Adding a box shadow to Individual Tabs Module breaks the Inspector – 4.0.4

Weird one.

Repro:

  1. Add a default Tab element to the page
  2. Click the Individual Tabs Module image
  3. Scroll down and click the toggle to turn on Box Shadow

Observed:
The Inspector will immediately throw the “Uh Oh” message, and you won’t be able to load the Individual Tabs module again for that element – unless you go into the Dev Console and add the ! to the tabs_tabs_box_shadow_dimensions field.

Here’s the console dump:

Thanks @devinelston

Fixed for next patch.
