  Log Message:
  -----------
  Assertion failure in RenderView::decrementRendersWithOutline
https://bugs.webkit.org/show_bug.cgi?id=247453

Reviewed by Simon Fraser.

The bug was caused by RenderElement::willBeDestroyed always calling decrementRendersWithOutline
regardless of whether the style had been initialized or not.

Only call decrementRendersWithOutline when the style had been initialized.
