[Seaside] RE: [ADD] WASelectTag>>enablementBlock

[Boris Popov]

Not sure what your scenario was exactly, but here I have a list that
goes,

Canada
US
---- (disabled)
Armenia
...
Canada
...
US
...
Zimbabwe

in which case 'selected' <option> came up twice during rendering phase
if you'd selected one of the duplicated countries on top and most
browsers would assume it's the latter one you want, so by correcting it
I fix two issues: semantically single list should only have one
'selected' option, but practically if you pick Canada, I want the list
to highlight Canada in the top portion, not the lower one.

Hope this helps,

-Boris
