If it is I think this is a clash between the old-skool image sizing attributes used by TinyMCE and modern CSS image sizing techniques. I think using CSS to size the images works.

Also, resizing images via either of those methods is rather inefficient, so resizing the images to the size the will be displayed is another solution.
To be pedantic, I think the i tag still works, since Bootstrap uses the good practice of not overspecifying it's CSS, so anything that matches .glyphicon should work, whether it's an i or a span.

They do however recommend span instead of i now, which is a change from 2.3. I'm not sure why, I assumed it was accessability related but can't quickly find any documentation as to why.

But, since the actual class names all changed too (partly for performance reasons) that's all academic as it's easy enough to change the span while changing the classes.
