fix: set initial value when setting UI value

[ph-fritsche]

What:

On user input set the initial value to determine on blur if there are uncommitted changes.

Why:
Closes #917

How:

Set the InitialValue when using setUIValue instead of on focus events.
Clear the InitialValue when the element loses focus.
