It might looks weird but it is the one which is working.
For example, for `{"font-size: 42px", "font-size: 22px"}`

`value` is 0.0
`svalue` is 42px, 22px
index false
lu.units px
so if I check 


return val instanceof CSS.FontSize size
                   && value == size.value
                   && index == size.index
                   && Objects.equals(lu, size.lu);



it will return equals `true `even though it should not be equal which is why I used `svalue`
