Description

Building the attached example will result in qmllint warnings (and therefore a failed build if qmllint is taken seriously).

Note the order of the qml files:

Main.qml
Foo.qml
Bar.qml

Bar uses Foo. If Bar is listed before Foo (or Main would also use Foo), the warning disappears.

execute qmllint command only with foo.qml => warning
execute qmllint command with bar.qml + foo.qml => no warning
execute qmllint command with foo.qml + bar.qml => warning

It seems the linter object in qmllint does not have a clean state for each invocation on the next file.

Also I don't understand why this warning is triggered at all. Looks a little bit like ~~QTBUG-104571~~, as QtQuick.Dialogs uses file selectors in its qmldir.
