AST Matcher binds wrong TypedefDecl object

I have this code:
`struct AnInterface {};`
`typedef AnInterface ABase1;`
`class AClass1 : public ABase1 {};`
`typedef AnInterface ABase2;`
`class AClass2 : public ABase2 {};`
And this ASTMatcher:
`cxxRecordDecl(`
` isDerivedFrom(`
` decl().bind("typedef")`
` )`
`).bind("record")`
The second match wrongly binds `AClass2` and **`ABase1`**.
The same behavior occurs with
`using ABase1=AnInterface`
Output of clang-query:
> clang-query> m cxxRecordDecl( isDerivedFrom( decl().bind("typedef") ) ).bind("record")
