Scoreboard empty lines bug

[Elb1to]

If the scoreboard contains empty lines, like the example shown below:

title: '&b&lHABU'
lines:
- '&7Welcome &b%player%'
- ''
- '&b&lPLAYERS'
- ' &7 • &f%online% players online'
- ''
- '&7elb1to.me'

The scoreboard won't show those empty lines, just the first one, the other empty lines won't appear, unless they have a color code in them like the example shown below:

title: '&b&lHABU'
lines:
- '&7Welcome &b%player%'
- '&2'
- '&b&lPLAYERS'
- ' &7 • &f%online% players online'
- '&6'
- '&7elb1to.me'

Current code:
