This wasn't done consistently (otherwise bug 1936194 wouldn't have worked). Now that we recreate the popups when needed, we can rely on that instead of reparenting the widget. Popups are the only type of widget we should ever reparent, as other widgets are created at the top level which can't be moved around.

|
// CoreAnimation transactions are per-thread. They don't nest across threads.
|
|
// If you submit a transaction on the main thread and a transaction on a
|
|
// different thread, the two will race to the window server and show up on the
|
|
// screen in the order that they happen to arrive in at the window server.
|
|
// When the window size changes, there's another event that needs to be
|
|
// synchronized with: the window "shape" change. Cocoa has built-in
|
|
// synchronization mechanics that make sure that *main thread* window paints
|
|
// during window resizes are synchronized properly with the window shape change.
|
|
// But no such built-in synchronization exists for CATransactions that are
|
|
// triggered on a non-main thread. To cope with this, we define a "danger zone"
|
|
// during which we simply avoid triggering any CATransactions on a non-main
|
|
// thread (called "async" CATransactions here). This danger zone starts at the
|
|
// earliest opportunity at which we know about the size change, which is
|
|
// nsChildView::Resize, and ends at a point at which we know for sure that the
|
|
// paint has been handled completely, which is when we return to the event loop
|

// after layer display.
