Interactive stack: Strange digit navigation behavior with more than 9 stack items

[mahi2003]

I like the way the digit navigation (#1029) is implemented - very quick to get to a known stack level - but once the stack gets deeper (>9 elements), the selection logic is a bit strange.

I have the impression that the current stack level is (wrongly?) used as first digit:

• Have 30 items on the stack
• Press up arrow to enter the interactive stack (level 1 is selected)
• Press 0 → Level 10 is selected
• EXIT
• Press up arrow to enter the interactive stack (level 1 is selected)
• Press up arrow once more to select level 2
• Press 0 → Level 20 is selected
• EXIT
• Press up arrow to enter the interactive stack (level 1 is selected)
• Press up arrow twice to select level 3
• Press 0 → Level 30 is selected

I know level 0 does not exist, bit it's just to indicate how it appears to work.

Here's with real stack levels:

• Have 30 items on the stack
• Press up arrow to enter the interactive stack (level 1 is selected)
• Press 1 → Level 11 is selected
• EXIT
• Press up arrow to enter the interactive stack (level 1 is selected)
• Press up arrow once more to select level 2
• Press 1 → Level 21 is selected
• EXIT
• Press up arrow to enter the interactive stack (level 1 is selected)
• Press 2 → Level 12 is selected
• EXIT
• Press up arrow to enter the interactive stack (level 1 is selected)
• Press up arrow once more to select level 2
• Press 2 → Level 22 is selected
• ...

Maybe this is by design, but I think it's counter-intuitive
