qmllint warns about missing-type for properties of type QVector<EnumClass>

A problem has been identified when using an enum class registered with the Q_ENUM_NS macro inside a namespace. The project also includes the Q_CLASSINFO("RegisterEnumClassesUnscoped", "false") directive. When a QVector of this enum type is used as a property, qmllint issues a "missing-type" warning. This issue does not occur if a QVector<int> is used instead.

Steps to Reproduce:

1. • Download the attached minimal example project that demonstrates the issue.

• • Open a terminal and navigate to the root directory of the example project.

• • Build the project using Qt’s build system  with cmake .

• • Run qmllint on the QML files in the project directory. 

Expected Behavior:
No warning should be issued by qmllint if the enum type is correctly registered and used.

Actual Behavior:
qmllint reports a "missing-type" warning for the QVector<EnumType> property.

Notes:
A minimal example reproducing the issue is attached.
