`WindowAttributes.with_visible(false)` ignored on Windows

### Description

Calling `.with_visible(false)` on a `WindowAttributes` to create a window on Windows will create a visible window. Instead, it should create a non-visible window. Perhaps this isn't supported on Windows? If so, adding the to documentation would be helpful.
