Partial selection of a table does not extend to the whole table

[evbacher]

There is code to extend a partial selection to include the parent elements (paragraphs, lists, etc.).

But if you selection only a portion of a table, the selection is not extended to the whole table.

Instead of

<table>
  <tr>
   <td> Some text...

you get

  <tr>
   <td>Some text...

This is a subtle issue, and it may be difficuult to process, but we should at least take a look at it. For now, note in the docs regarding partial selection: https://github.com/evbacher/gd2md-html/wiki#partial-selection
