You can open your browser and you should be able to see the changes you've made in the code.

Because of it, we need to fill all\n * empty elements which should be selectable with elements or characters called \"fillers\". Unfortunately there is no one\n * universal filler, this is why two types are uses:\n *\n * * Block filler is an element which fill block elements, like `

    `. CKEditor uses `
    ` as a block filler during the editing,\n * as browsers do natively. So instead of an empty `

    ` there will be `


    `. The advantage of block filler is that\n * it is transparent for the selection, so when the caret is before the `
    ` and user presses right arrow he will be\n * moved to the next paragraph, not after the `
    `. The disadvantage is that it breaks a block, so it can not be used\n * in the middle of a line of text. The {@link module:engine/view/filler~BR_FILLER `
    ` filler} can be replaced with any other\n * character in the data output, for instance {@link module:engine/view/filler~NBSP_FILLER non-breaking space} or\n * {@link module:engine/view/filler~MARKED_NBSP_FILLER marked non-breaking space}.\n *\n * * Inline filler is a filler which does not break a line of text, so it can be used inside the text, for instance in the empty\n * `` surrendered by text: `foobar`, if we want to put the caret there. CKEditor uses a sequence of the zero-width\n * spaces as an {@link module:engine/view/filler~INLINE_FILLER inline filler} having the predetermined\n * {@link module:engine/view/filler~INLINE_FILLER_LENGTH length}. A sequence is used, instead of a single character to\n * avoid treating random zero-width spaces as the inline filler. Disadvantage of the inline filler is that it is not\n * transparent for the selection. The arrow key moves the caret between zero-width spaces characters, so the additional\n * code is needed to handle the caret.\n *\n * Both inline and block fillers are handled by the {@link module:engine/view/renderer~Renderer renderer} and are not present in the\n * view.\n *\n * @module engine/view/filler\n */\n\n/**\n * Non-breaking space filler creator.
