Please focus on the range of the nodes.

Repro Code

@foo({name:1,})exportclassFoo{}

Expected Result

• RunsourceCode.getNodeByRangeIndex(14)
• ReturnProperty

Actual Result

ReturnProgram

Additional Info

When aClassDeclaration has a parent node of typeExportNamedDeclaration orExportDefaultDeclaration,sourceCode.getNodeByRangeIndex fails to return the correct node based on the provided index.

This occurs because the range ofExportDeclaration andClassDeclaration nodes does not include the range of decorators, causing decorators to be skipped during node retrieval.

This appears to be a design limitation in the ESTree specification. However, is it possible to override thegetNodeByRangeIndex to ensure it returns the correct node in such cases?
