   ### Steps to reproduce
   Add the emphasis styling code to any link object.
   
   ```
   option = {
       series: {
           type: 'sankey',
           layout:'none',
           focusNodeAdjacency: 'allEdges',
           data: [{
               name: 'a'
           }, {
               name: 'b'
           }, {
               name: 'a1'
           }, {
               name: 'a2'
           }, {
               name: 'b1'
           }, {
               name: 'c'
           }],
           links: [{
               source: 'a',
               target: 'a1',
               value: 5,
               emphasis: {
                   lineStyle: {
                       color: '#ff0000',
                       opacity: .99
                   }
               }
           }, {
               source: 'a',
               target: 'a2',
               value: 3
           }, {
               source: 'b',
               target: 'b1',
               value: 8
           }, {
               source: 'a',
               target: 'b1',
               value: 3
           }, {
               source: 'b1',
               target: 'a1',
               value: 1
           }, {
               source: 'b1',
               target: 'c',
               value: 2
           }]
       }
   };
   ```
   
   ### What is expected?
   The link from a -> a1 should be red with 99% opacity when you hover.
   
   ### What is actually happening?
   The styling of the link remains set to default.
