vi: ignorecase not working when regex enabled

1)
compile regex DISABLED
set ignorecase
search for something using lowercase in a file with mixed case
search finds both lower and upper case words

2)
compile regex ENABLED
set ignorecase
search for something using lowercase in a file with mixed case
search finds only lowercase words
