Bug 62720

When a document starts with a table, "Select All" is ineffective for selecting all the text in the document, no matter how many times it is repeated.

To reproduce, create a document like the following:
1. Single cell table containing text (at the very start of the document, no preceding text or newline)
2. Following text outside table

Whether the cursor is initially placed inside or outside the table, repeating "Select All" cycles between selecting the content of the table cell and the table cell itself; the following text outside the table is never selected.



Compare with the following case with correct behaviour:
1. Single newline
2. Single cell table containing text
3. Following text outside table

In this case, when "Select All" is performed outside the table, all text both inside and outside the table is immediately selected. When performed repeatedly from inside the table, the progression

   All text in cell selected -> Whole cell selected -> All text in document selected

results, as expected.



Reproduced on both OSX and Linux
