Thank you for submitting the issue!

I was able to reproduce it. There shouldn't be a space between those elements. This is currently happening because of the checkbox using a flex style.

While a fix is being worked on, you can use the following style as a workaround:

ion-item ion-checkbox {
  flex: initial;
}

radio buttons are also affected:

ion-item ion-checkbox, ion-item ion-radio {
  flex: initial;
}
