Grid vertical alignment is not on working on IE10/11 if the row has a min-height

Created by: AlexWebLab

We should add a note on the documentation here: https://getbootstrap.com/docs/4.0/layout/grid/#vertical-alignment to alert the reader that the grid vertical alignment is not working on IE10/11 if the row has a min-height because of the following flexbug: https://github.com/philipwalton/flexbugs#flexbug-3

p.s.: the example itself is not working on IE10/11
