datetime-local, date, month, time <input>s are taller than other <input>s in Chrome/Edge

Created by: heruan

Why inside an input-group the input type datetime-local gets a different height from other form-controls? See https://jsfiddle.net/02z6gh62/2/ (I'm using Chrome)

I've found this

@media screen and (-webkit-min-device-pixel-ratio: 0)
.input-group-sm input[type=date].form-control,
.input-group-sm input[type=time].form-control,
.input-group-sm input[type=datetime-local].form-control,
.input-group-sm input[type=month].form-control,
input[type=date].input-sm, input[type=time].input-sm,
input[type=datetime-local].input-sm,
input[type=month].input-sm {
    line-height: 1.95rem;
}

and setting line-height to 1rem works perfectly fine in Chrome, then I wonder why it's forced to 1.95.
