Description

When using JsDiagGetProperties() to inspect an object in the debugger, is there a way to get the property attributes (writable, configurable, enumerable) for each property? I thought that was what propertyAttributes was for, but that's not the case:

    ///     propertyAttributes is a bit mask of
    ///         NONE = 0x1,
    ///         HAVE_CHILDRENS = 0x2,
    ///         READ_ONLY_VALUE = 0x4,
