The name |GetTopControlsShrinkBlinkSize| is really confusing. "get...size"
sounds like it should return a number.

Yeah I can see that being a bit confusing.  I could call it
getTopControlsShrinkBlinkViewport, but that still kind of makes it sound like it
should return a Rect or a Size object.  Maybe getTopControlsShrinkBlinkLayout?

+  if (!content_view_core_)
+    return false;
+
+  // Whether or not Blink's viewport size should be shrunk by the height of the
+  // URL-bar.
+  return content_view_core_->GetTopControlsShrinkBlinkSize();
+}
+
+float RenderWidgetHostViewAndroid::GetTopControlsHeight() const {
   if (!content_view_core_)
     return 0.f;
 
-  // The amount that the viewport size given to Blink is shrunk by the URL-bar.
-  return content_view_core_->GetTopControlsLayoutHeightDip();
+  // The height of the top controls.
+  return content_view_core_->GetTopControlsHeightDip();
 }
