Views admin CSS hides important elements on e.g. Display Suite vertical tabs

When I view the Display Suite field layout for a display with custom regions, the "remove custom regions" block is made display: none. This is because of the following CSS at line 46 in views-admin-rubik.css

/* Hide 'remove' checkboxes. This might be scoped too widely. */
[class*="form-type-checkbox"][class*="remove"] {
  display: none;
}

Prescient comment there: it does indeed seem to be scoped too widely! It's targeting an element with the otherwise innocuous class of:

form-item form-type-checkboxes form-item-additional-settings-region-to-block-remove-block-region

This CSS declaration needs to be more tightly scoped, as it currently breaks pages like the DS admin interface. That [class*="remove"] is the cause for concern - "remove" can mean all sorts of things depending on context! - but it can probably be fixed by just adding some more classes based on what we expect this CSS to apply to.

Does anyone have any examples of what views-admin-rubik.css is trying to do here? If you can volunteer one, and you can transcribe Google Chrome's path to element (right-click to Inspect Element, and read the classes and IDs off the bottom status bar) then that'd help work out what classes to add to this declaration.
