Debug break at abort() during QTextEdit layout

// Settings:
// - Qt 5.12.0.
// - MinGW 7.3.0 64-bit.
// - Debug with GDB option 'Stop when abort() is called'.
//
// Observation:
// Setting QTextEdit as QMainWindow central widget
// causes anomalous debugger break at QWidgetAnimator::abort()
// when window is shown and/or layout is recalculated.
// Behavior different than all earlier Qt versions.
