Reproducible via:

class test {
    static {
        console.<ctrl+space>
    }
}

The intellisense/autocomplete window doesn't show. It's unable to discern properties of any object inside of a static block.

I'm not sure if this is dissimilar to microsoft/vscode#138256 and microsoft/vscode#46587 but the stack trace slightly differs, so maybe?

    This appears to have been addressed in 4.6, as it no longer repros in 4.6 or later.
