TextAngular和Rangy类和id

Question

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> 

如何禁用此功能？如果它根本不应用anny样式，那很好，我只是想摆脱那些css类和id。
