Doesn't recognize type declarations when preceded by using.

I had this:

using SingleTestMessageType :: enum u16 {
    SINGLE_TEST_MESSAGE;
    NUM_SINGLE_TEST_MESSAGE_TYPES;
}

but the language server couldn't see the type. I changed it to this:

SingleTestMessageType :: enum u16 {
    SINGLE_TEST_MESSAGE;
    NUM_SINGLE_TEST_MESSAGE_TYPES;
}
using SingleTestMessageType;

and it works fine. Not sure how difficult this would be to fix, considering how many places using can show up, but figured I'd report it.
