This is a follow-up patch for https://codereview.chromium.org/448593002 to fix a crash. The previous patch uses renderer.slowFirstChild() to get an child renderer in computeQuads(). However, this is not always correct. For example, suppose that <a><div></div></a> is given, the render tree would be: RenderBlock (anonymous) 0x6110004a6400 RenderInline 0x60c00014e6c0 A 0x60d00006cf10 RenderBlock (anonymous) 0x6110004a6180 RenderBlock 0x6110004a62c0 DIV 0x60b00004d930 CLASS="_muf" In this case, there is no child renderer for RenderInline object(0x60c00014e6c0). Instead, LinkHighlight::computeQuads() should use a composed tree based traversal to compute quads correctly because we've already used a composed tree based traversal to get an parent object in the previous patch.
