Floating label example has misaligned label due to change of height of inputs

Created by: Ruffio

I was thinking of using the floating label on my website, but it appears to have been changed :-(

4.0 (https://getbootstrap.com/docs/4.0/examples/floating-labels/):

4.1 (https://getbootstrap.com/docs/4.1/examples/floating-labels/):

Actually I think that the changes happened when 4.1.3 was released and a fixed height of 38px was introduced as it goes from 50px (calculated) to 38px (set):
