Test that WebKit does not crash when we apply style to atomic elements and that the style is not applied inside atomic elements.
| <a>
|   href="a"
|   "<#selection-anchor>1"
|   <progress>
|     <a>
|       style=""
|       "2"
|     <shadow:root>
|       <div>
|         pseudo="-webkit-progress-inner-element"
|         shadow:pseudoId="-webkit-progress-inner-element"
|         <div>
|           pseudo="-webkit-progress-bar"
|           shadow:pseudoId="-webkit-progress-bar"
|           <div>
|             pseudo="-webkit-progress-value"
|             style="width: -100%;"
|             shadow:pseudoId="-webkit-progress-value"
|   <#selection-focus>
