10073	ACF should clean up empty elements	Piotrek Koszuliński		"TC:

1. Create editor without image button (e.g. use one of editors in filter sample).
2. Switch to source.
3. Set: {{{<p><em><img src="""" alt=""""></em></p>}}}.
4. Switch to wysiwyg mode.
5. Check with dev tools that editable contains {{{<p><em></em></p>}}}.


There are few cases:
* {{{<b><img></b>}}}: after filtering out {{{<img>}}} entire {{{<b>}}} should be removed, because it's in {{{DTD.$removeEmpty}}}.
* {{{<a href=""""><img></a>}}} is a different case because it's similar to {{{<a name=""""><img></a>}}} and {{{<a name=""""></a>}}} shouldn't be removed. So it's an exception, because 'a' isn't included in {{{$removeEmpty}}}. However, why doesn't data processor fix this case? It fixes the case I described in the next point, but why not this? Especially, that I see a filter's rule for htmlFilter that fixes this on output. I think that identical rule should exist for toHtml(). And perhaps previous point should also be handled by data processor...
* {{{<p><img></p>}}}}: after filtering out {{{<img>}}} filter will left empty {{{<p></p>}}} which then will be correctly handled by data processor, so in this case we don't have to act.
