I prefer this line to move right above line 114 below, so related things are
close to each other.

Done.

     text_style = node->GetIntAttribute(ui::AX_ATTR_TEXT_STYLE);
+
+    // The font size is just the computed style for that element; apply
+    // transformations to get the actual pixel size.

+    gfx::Rect scaled_text_size_rect = node->RelativeToAbsoluteBounds(

+    size = scaled_text_size_rect.height();
   }
 
   const gfx::Rect& absolute_rect = node->GetPageBoundsRect();
