When having the following widget structure:
QWidget / QStackedLayout
-> QScrollArea [widgetResizable = true]
--> QWidget / QBoxLayout (or QGridLayout) [sizeConstraint = SetFixedSize]
---> QPushButton
And resizing the Widget before calling show, causes infinite resize loop due to scrollbars calling setGeometry().

The loop looks like:

• QScrollArea::resizeEvent
  ↓
• QScrollAreaPrivate::updateScrollBars
  ↓
• QAbstractSlider::setRange (2 times)
  ↓
• rangeChanged signal emitted
  ↓
• slot QAbstractScrollAreaPrivate::_q_showOrHideScrollBars
  ↓
• QAbstractScrollAreaPrivate::layoutChildren
  ↓
• QWidget::setGeometry
  ↓
• QResizeEvent send
  ↓
• Return to first; QScrollArea::resizeEvent

This problem does not reproduce if show() is called before the resize() for the widget. Documentation states that calling resize() before show() is allowed, but the scrollbars are calling setGeometry(), which is forbidden inside the ResizeEvent according to the documentation.

Steps to reproduce:

• Run attached sample
• Press "Clone" button to create a new widget with specified size
• EXPECTED: Widget is properly created and shown
• ACTUAL: Widget is created, but enters an infinite loop of ResizeEvents
