Custom control border color missing on focus and checked

Created by: QballDevelop

Focus border color is missing when a custom checkbox is checked.

It's because of the following line of code:

&:focus:not(:checked) ~ .custom-control-label::before {
  border-color: $custom-control-indicator-focus-border-color;
}

It should be without :not(:checked)

Resulting in:

&:focus ~ .custom-control-label::before {
  border-color: $custom-control-indicator-focus-border-color;
}
