This test ensures that virtual specifiers are correctly propagated from the QML source code into the
intermediate representation (IR).
Due to the current design, it is difficult (if not impossible) to test
IRBuilder::visit(UiPublicMember*) in complete isolation.
Therefore, this test takes an end-to-end (E2E) approach: it constructs a valid QML object
declaration containing a property with the relevant specifier keywords, builds the IR for it, and
then verifies that the resulting property node in the IR has the expected flags.*/
