This is changed behaviour from Beta 4 to Beta 5 even though the css though would indicate otherwise:
It looks like the following css is overriding it:
Code:
#SignupButton:hover span {
@property "signupButtonHover";
text-decoration: none;
It looks like the following css is overriding it:
Code:
a.concealed:hover, .concealed a:hover {
text-decoration: underline !important;
