“Invalid email” if a space is at the end of the adress

Hi,
If i type a space at the end of the adress email, there is an error message “invalid email”.
A space can be automatically typed when using mobile device like android phone with some keyboard app. In my case i use “Swiftkey” and if start to type my email adress, it display a prediction, if i choose ite, all my email adress email is typed..but with a space at the end.
Could you make the plugin ignore space at the end ?
Thanks
