Description:
If I do "convert text to table" in RTL mode and then try to add a border to the table, the left side border (at the "end" of the RTL table) cannot be added.

Steps to Reproduce:
1. Make sure Complex Text Layout is on. Set to RTL mode.
2. Type a;b;c.
3. Select the text a;b;c.
4. Go to Table | Convert Text to Table. Set "Separate Text At" to Semicolons. Hit OK.
5. Put the cursor in the table you just created. Right-click and select Table Properties | Borders. Under Line Arrangement, select any of the presets that have an outside border. Hit OK.
6. Notice that the left-hand border doesn't exist.
7. Select the entire table. Right-Click | Table Properties | Borders. Under Line Arrangement | User-defined, notice that the left-hand border isn't selected. Select it and hit OK.
8. Notice that the left-hand border still doesn't exist.

Actual Results:
Left-hand border isn't created and can't be added.

Expected Results:
Left-hand border should have been created.
