UI enhancement fixes 2 (#3225)

- Fixed incorrect CSS naming: `c-frame-edit__move` changed to
 `c-frame__move-bar`;
 - Fixed `display: contents` that was erroneously applied to
 `u-angular-object-view-wrapper` and preventing styling from being
 applied to plots, renamed class to `.l-angular-ov-wrapper`;
 - Removed commented CSS;
