I can't tell if this is the right fix (createLspRangeFromNode -> getRangeOfNode) or if this is the right fix: https://github.com/microsoft/typescript-go/pull/1326/files#diff-4cd7fcdded6dbd561658f34fe1abb4030739555b30d90785a6ba6f08aec0d523R393

The proposed fix is to apply the same normalization used by ts in toReferenceEntry for non-span entries.

function getTextSpan(node: Node, sourceFile: SourceFile, endNode?: Node): TextSpan {
    let start = node.getStart(sourceFile);
    let end = (endNode || node).getEnd();
    if (isStringLiteralLike(node) && (end - start) > 2) {
        Debug.assert(endNode === undefined);
        start += 1;
        end -= 1;
    }
    if (endNode?.kind === SyntaxKind.CaseBlock) {
        end = endNode.getFullStart();
    }
    return createTextSpanFromBounds(start, end);
}

While tsgo has a similar utility, it wasn't used in the find-all-references results.

Lines 257 to 274 in 15def02

	func (l *LanguageService) getRangeOfNode(node *ast.Node, sourceFile *ast.SourceFile, endNode *ast.Node) *lsproto.Range {
	if sourceFile == nil {
	sourceFile = ast.GetSourceFileOfNode(node)
	}
	start := scanner.GetTokenPosOfNode(node, sourceFile, false /*includeJsDoc*/)
	end := core.IfElse(endNode != nil, endNode, node).End()
	if ast.IsStringLiteralLike(node) && (end-start) > 2 {
	if endNode != nil {
	panic("endNode is not nil for stringLiteralLike")
	}
	start += 1
	end -= 1
	}
	if endNode != nil && endNode.Kind == ast.KindCaseBlock {
	end = endNode.Pos()
	}
	return l.createLspRangeFromBounds(start, end, sourceFile)
	}

It would be helpful to see cases involving CaseBlock or StringLiteralLike...
