On further triage, I observed following-

• In style.js removeFromElement() function, while executing following line

if ( this._.definition.fullMatch && element.getStyle( styleName ) != normalizeProperty( styleName, styles[ styleName ], true ) )

continue;

normalizeProperty() returns value as '#004' where as element.getStyle() returns '#000044'. This results in mismatch and styles are no removed.

• Please note the following default configuration in Find plugin.js

CKEDITOR.config.find_highlight = { element: 'span', styles: { 'background-color': '#004', color: '#fff' } };

• If we override the configuration using following, the issue does not occur. - CKEDITOR.replace( 'editor1',{find_highlight : { element: 'span', styles: { 'background-color': '#000044', color: '#fffffF' }}} );

So there is a workaround to the problem. However, I am not sure if this issue would affect other functionalities.
