 - As a fix to QTBUG-50992, execution of delegates, such as contentItem and
   background, is deferred until the construction of a control is complete,
   or a delegate is accessed. Consequently, if a delegate is replaced with
   a custom delegate, the default delegate is not created. Previously, when
   a default delegate was replaced by a custom delegate, the default
   delegate was nevertheless created and destroyed during the construction
   of the control.

****************************************************************************

 - [QTBUG-64548] Fixed shortcuts in QQuickWidget

 - [QTBUG-65016] Fixed QQuickStyle::setFallbackStyle() in static builds

 - [QTBUG-50992] Fixed a bug which caused delegates of customized controls
   to often be "destroyed during incubation" when asynchronously incubated
   by item views or asynchronous loaders.

 - BusyIndicator:
   * [QTBUG-62874] Fixed busy animation in QQuickWidget

 - ProgressBar:
   * [QTBUG-62874] Fixed indeterminate animation in QQuickWidget

 - StackView:
   * [QTBUG-65084] Fixed to not block touch events.

 - SwipeView:
   * [QTBUG-62110] Fixed slow swiping in large views

 - ToolButton:
   * [QTBUG-65052] Fixed round ripple for square buttons in the Material style

 - Tumbler:
   * [QTBUG-65165] Made currentIndex animations take a constant amount of
     time (1 second) regardless of how many items are in the model. This
     prevents Tumblers with large amounts of items from scrolling too
     slowly when changing the currentIndex.
