Description:
When both outer border and horizontal inner lines are styled in the Borders tab of the Table Properties dialog of a floating table that spans at least two pages, the inter-page virtual outer borders are not rendered as outer borders but instead as inner line styles.

This problem is not reproduced if only vertical inner lines are styled.

Steps to Reproduce:

1. Create a new text document.
2. Select Table > Insert Table... menu option to open the Insert Table dialog.
3. In the Insert Table dialog:
    + In the General section:
        - Fill in `2` in the Columns text field
        - Fill in `60` in the Rows text field. (Increase the number if the resulting table does not span 2 pages)
4. Click the Insert button at the bottom of the window to insert the table and close the Insert Table dialog, this should create a big table that spans 2 pages(if not, adding new rows to the table until it do).
5. Select any cell in the table, then select the Table Properties... option in its contextual(right-click) menu.
6. In the Table Properties dialog, select the "Outer Border Only" preset(check the tooltip of each option) in the Line Arrangement > Presets field of the Borders tab, then set the Thickness field in the Line section to Thick (2.25pt) for better observation of the outer borders.  Then click the horizontal inner line in the Line Arrangement > User-defined graph then set the Thickness field in the Line section to Very thin (0.5pt).
7. Click the OK button at the bottom to apply the settings and close the Table Properties dialog.
8. Observe the _bottom_ virtual table border of page 1 and the _top_ virtual table border of page 2.


Actual Results:

The _bottom_ virtual table border of page 1 and the _top_ virtual table border of page 2 are not rendered in the outer border style but instead similar to the horizontal inner lines.


Expected Results:

The _bottom_ virtual table border of page 1 and the _top_ virtual table border of page 2 are rendered in the outer border style.
