Hello,
I just upgraded an application to latest JS API 4.14 and noticed a small bug with the directions widget: <wbr> html markup is visible between the distance and the time. It is easily reproducible using the following sample:
Directions widget | ArcGIS API for JavaScript 4.14

On a side note, I find it a bit confusing that minutes' abreviation is "m" rather than "min".
Thanks !
