ppc64le: select does not work

[rck]

Hi,

if I compile select in _examples with "GOARCH=ppc64le", and execute it on a POWER machine it does not work as expected and shows the following behavior:

• when I press j it prints a j at the bottom of the list and does not update the TUI (i.e., does not move the "selection arrow". If I do the same with the "down-key", I see the key-code of that key at the bottom.
• when I finally press enter, the correct item is selected. For example if I press jj, I see these two jjs at the bottom, then I press <enter> and it prints You choose "Wednesday".

Do you think this updating bug is a bug in promptui or actually a bug in one of the dependencies? Any hints are welcome.
