Don't crash when hiding top-level windows (#3757)
Current window management approach results in secondary windows being
destroyed once they are hidden. Since those windows are managed by
`std::unique_ptr<>`, we can't just [temporarily] increase their refcount
to avoid use-after-free situation, so retrieve updated top-level windows
list every time we hide one instead.
