Behavior of inserts with unknown attributes

5

**Describe the bug** When attributes are unknown to the renderer it does not render the text, just a newline **The delta code which generates the Problem** ``` {"ops":[{"insert":"1"},{"attributes":{"unknownAttribute":{"id": 123}},"insert":"2"},{"insert":"3"},{"insert":"\n"}]} ```...

I find myself writing a lot of `$param = $request->hasAttribute('name') ? $request->getAttribute('name') : null;` Would you consider adding this feature?
