WEmailValidator fails when domain name contains a hyphen
The new WEmailValidator introduced in Wt 4.10.0 does not allow hypens in the domain name.
Thus it rejects valid email adresses if they contain a hyphen in the domain name.
firstname.lastname@example.org > Is OK
email@example.com > Is rejected (see screenshot attached)
I see this behavior in Firefox and MS Edge and it can be reproduced using the Email Edit section in Wt Widget Gallery.
