+Subject: fix: initial occlusion state on macOS
+
+With the new occlusion detection enabled via
+https://chromium-review.googlesource.com/c/chromium/src/+/5605407
+starting the window as hidden previously resulted in
+Visibility::kOccluded (via viewDidMoveToWindow) -> Visibility::kHidden (via viewDidHide)
+but it now starts with Visibility::kVisible -> Visibility::kHidden
+which throws off the initial document.visibilityState checks.
