You cannot change a non-terminal element without changing its contents.
In particular plain-lists, tables and paragraphs are fully defined by
their contents, i.e., they do not decorate contents like headlines. In
this case, data returned by `org-element-context' is incomplete in this
case. You probably need to parse the buffer between :begin and :end and
modify structure recursively.
