When accessing fx table there are always two focused rows even if the table itself is not focused.

Reproducible: always
Platform-dependent: no,
Is a regression: yes
Introduced in build: 8u25b10

Steps to reproduce (sample attached):
1. Create TableView or TreeTableView and add some data into it
2. Select rows using lookupAll(".table-row-cell") or lookupAll(".tree-table-row-cell")
Expected:
- There is always none or one focused row.
Actual result:
- There are always two rows that are visible (row.isVisible()) and focused ((row.isFocused()). One of that rows always has "-1" index.

Is it an expected behavior?
