Unexpected warning about a component being neither used nor exported

[hunger]

Bug Description

I get a warning in my slint code that I do not expect:

Component is neither used nor exported [Ln 1, Col 1]

Reproducible Code (if applicable)

component Foo /* Foo 1 */ { }

export component FooBaz {
    Foo /* <- TEST_ME_1 */ { }
}

component Foo /* Foo 2 */ { }

export component Baz {
    Foo /* <- TEST_ME_2 */ { }
}

Environment Details

• Slint Version: master
• Platform/OS: Linux
• Programming Language: Not applicable
• Backend/Renderer: Not applicable

Product Impact

I guess it should be an error that Foo is already defined?

Funny thing is that if we do NOT use Foo 1 (by commenting the line with TEST_ME_1), then we don't get that warning.
