Bug: Cursor position gets lost when integration tab into window

[Frank Rohde]

Version: 7.5.6

performed actions:
- excluded tab into new nppp window by dragging and dropping tab-symbol out of original nppp window
- edited tab in the nppp window, thereby changing its cursor position
- included tab into original nppp window again using drag and drop

Experienced Behaviour:
- tab exclusion into new npp window keeps cursor position
- tab inclusion into existing npp window looses cursor position (cursor jumps to line 1)

Expected Behaviour:
- both, tab exclusion and tab inclusion keep cursor position

I hope, you can reproduce this and can fix it in a future release. Thanks

Frank
