14369	Inline Widget - Downcast/Upcast errors	Gavin Roberts		"== Steps to reproduce ==

1. Go to https://jsfiddle.net/zkv6pme3/3/
2. Place cursor within text.
3. Click empty button on the left (note the red bordered box that appears)
4. Click the Source button

== Expected result ==

1. All `<span class=""test""></span>` blocks to be upcasted and converted into widgets.
2. When clicking Source after adding a widget to the editor, it should show the source code.

== Actual result ==

1. Existing `<span class=""test""></span>` blocks are removed.
2. Throws `Uncaught TypeError: Cannot read property 'attributes' of null`
