Description:
A cell contains, e.g., '123'.

Click Backspace from the end and it becomes '12'.

Repeat and it's '1'.

But if I Backspace to remove the last character it changes back to '123', as if I had not deleted it at all, and now Backspace no longer has any effect.
The '123' displayed isn't really there: if I hit Enter then the cell is empty. If I type a digit then the digit replaces it.

Because it's so obvious, I have to wonder whether this is deliberate. If so, what is the thinking behind it?


Steps to Reproduce:
1. Enter '123' in a cell
2. Delete each digit
3. See '123' reappear.

Actual Results:
'123' reappears.

Expected Results:
An empty cell, reflecting the fact that the number has been deleted.
