Unable to select the text in IE browsers in Ionic

问题:

When I'm trying to select text with the mouse on my website with internet explorer (IE10 and IE11), I just can't figure out why

By default Ionic is disabled text selection. I am overriding ionic classes with following code.

       body{     
          -moz-user-select: text;
          -webkit-user-select: text;
          -ms-user-select: text;
          -o-user-select: text;
          user-select: text;
    }

It is working for chrome, firefox and opera, but not working for IE.

Does have anybody an idea how to fix this? I've already search for similar problem but no answer.

Thanks all for answers
