Regression
Yes
Viewport content position values breaks to NaN value when changing Scroll Rect position (can not undo)
Reproduction steps:
1. Open project attached (ScrollRectTest.zip).
2. Open scene "test".
3. Press on Scroll Rect (in Canvas).
4. Drag it by X.
Expected result: Scroll Rect moves with all its content.
Actual result: Content (Scroll Rect -> Viewport) rect transform position breaks (becomes NaN) and unable to undo it.
Reproduced on: 5.6.0b2, 5.6.0b7, 5.6.0b9.
Works fine in: 5.5.1p4, 5.6.0b1.
Regression introduced in: 5.6.0b2.

After spending hours of rebuilding my UI elements, it went crazy again. Sometimes the position values turn to NaN, sometimes overly large numbers when set to 0. It feels like the whole UI system is hanging on a thin piece of thread ready to snap at any moment.

Happening in Unity 5.6.0f3, project broken, scroll rects unusable, and I have quite many of them in my project, half the game is broken because of that.

Update to the previous comment I made. Resolved issue whereby inactive objects weren't fixed.
Hope this will help.
