Empty string was return when the event data is a '\n'

When server just sends '\n' among other events, the parsed event.data is just a empty string ''. For example:

from server:

[{id:1,data:'a'}, {id:2,data:'\n'}, {id:1,data:'c'}, ]

parsed messages:

[{id:1,data:'a'}, {id:2,data:''}, {id:1,data:'c'}, ]

the second parsed event data is different from server's.

这个库似乎没人管的样子

Ran into this issue in 2025. This is the only simple solution I could find. Would be good to find another event source library that solves this.
