MudCodeInput: inputs are not working well #613
Description
i found several issues on the MudCodeInput.
- first, sometimes we have to type more than 1 characters on the first input for it to move the focus to the next input.
- also on desktop, when the first input is empty and you keep pressing the backspace button it gets bugged and do not take you to the next input when you type until you click on it manually.
- on mobile, after typing keyboard always gets resetted, it gives a really bad UX when the code is a serie of numbers since it always switch the keyboard to characters instead of numbers.
- the backspace bug exist on mobile too but it does not glitch the input entirely, it just requires to type 2 characters instead of 1 for it to take the focus to the next input.
- the order of characters deletion on mobile is not working properly, seems that it starts deleting from the before last input.
