[oshihirii]

jsFiddle

Steps to replicate:

Select "ap" from select element and click show

ap will be added as the value of the input and horsey will show correctly

Click hide

Select "ba" from select element and click show

ba will be added as the value of the input and horsey will show incorrectly
the suggestion for apple is still showing, and not banana
