trap is not executed when interrupting a sleep command

[sidec15]

In my .bashrc file I have the following

function cleanup() {
  echo "Global cleanup"
  for i in {1..2}; do
    echo $i
    sleep 1
  done
  
}

trap cleanup SIGINT

function infinite_loop() {
  local i=1
  while true; do
    echo "hello $i"
    i=$((i + 1))
    sleep 1
  done
}

I basically want to execute some cleanup code after typing Ctrl+c
If I type Ctrl+c in a msys shell the trap correctly works but if I run the infinite_loop function and then type Ctrl+c the cleanup code is not executed also if the infinite_loop is stopped.

I tried also to add the option:
MSYS=enable_pcon
in the .minttyrc file after reading this: mintty/mintty#56 (comment) without success.
The version is msys2-runtime 3.4.10-5
