To reproduce the bug, I created a simple HTML file "a.html", and the content is as following:

<div style="border: solid red">a</div>

Then I try to get the individual border styles, and use a program like the following:
---------------------------------------------------------------------
StructuredTextEditor sse = (StructuredTextEditor) _targetEditor;
IDOMModel model = (IDOMModel) sse.getModel();
IDOMElement ele = (IDOMElement) model.getDocument().getDocumentElement();

CSSQueryTraverser traverser = new CSSQueryTraverser();
traverser.setElement(ele, null);
ICSSStyleDeclaration decl = traverser.getDeclaration();
StringBuffer buffer = new StringBuffer();

buffer.append("decl.getPropertyCSSValue(\"border-left-style\"): " + decl.getPropertyValue("border-left-style") + "\n");
buffer.append("decl.getPropertyCSSValue(\"border-right-style\"): " + decl.getPropertyValue("border-right-style") + "\n");
buffer.append("decl.getPropertyCSSValue(\"border-top-style\"): " + decl.getPropertyValue("border-top-style") + "\n");
buffer.append("decl.getPropertyCSSValue(\"border-bottom-style\"): " + decl.getPropertyValue("border-bottom-style") + "\n");

System.out.println(buffer);

--------------------------------------------------------------------
The output is like following:

decl.getPropertyCSSValue("border-left-style"): solid
decl.getPropertyCSSValue("border-right-style"): null
decl.getPropertyCSSValue("border-top-style"): solid
decl.getPropertyCSSValue("border-bottom-style"): solid

--------------------------------------------------------------------

Notice that for the "border-right-style" the result is "null"!

If I remove the "red" to change the HTML source to: 
<div style="border: solid">a</div>

The output will be:

decl.getPropertyCSSValue("border-left-style"): null
decl.getPropertyCSSValue("border-right-style"): null
decl.getPropertyCSSValue("border-top-style"): null
decl.getPropertyCSSValue("border-bottom-style"): solid

After some investigation, I believe the problem is relation to the usage of "CSSStyleDeclItemImpl.java#sharedStructuredDocument". "sharedStructuredDocument" is shared, but seemed something wrong with it. If I comment out line 234 of CSSStyleDeclItemImpl to disable sharing, then everything works fine.

//	if (sharedStructuredDocument == null) {
		IDocumentLoader loader = new CSSDocumentLoader();
		sharedStructuredDocument = (IStructuredDocument) loader.createNewStructuredDocument();
		((CSSSourceParser) sharedStructuredDocument.getParser()).setParserMode(CSSSourceParser.MODE_DECLARATION_VALUE);
		
//	}
