Title: Preview offset after switch fix choco butter ui

Changes
---
1. Refactored InfoBubbleViewModel (IBVM) to stabilize it and remove ambiguity
2. Shifted initial value set up to constructor of IBVM to centralize everything.
3. Added a on load event handler to InfoBubbleView to set up initial environment
This also resolves a bug that causes preview bubbles to show up when switching between tabs. (MAGN-810)
