angularjs - TextAngular 和 Rangy 类和 id

Question

对于本文

something something something
new line new line new line

textAngular 生成以下 html：

<p>something something something<br/>new line new line new line<br/></p> 

但是，如果我从两行中选择文本并在其上应用某些内容，则会生成以下 html：

<p>something <span id="selectionBoundary_1474901783760_9132792101106602" class="rangySelectionBoundary">&#65279;</span>something something<br/>new line new line<span id="selectionBoundary_1474901783759_6091248845512363" class="rangySelectionBoundary">&#65279;</span> new line<br/></p> 

我怎样才能禁用它？如果它根本不应用 anny 样式也没关系，我只想摆脱那些 css 类和 id。
