What happened?

I’m trying to set settings from FluidTerm, but since v3.9.8, settings are not set as what I want. Here’s the success log on v3.9.7 and failure log on v3.9.8 (both fresh installed):

Grbl 3.9 [FluidNC v3.9.7 (wifi) '$' for help]
> $HOSTNAME
$Hostname=fluidnc
ok
> $HOSTNAME=aaa
ok
> $HOSTNAME    
$Hostname=aaa
ok
> $HOSTNAME=bbb
ok
> $HOSTNAME    
$Hostname=bbb
ok

Grbl 3.9 [FluidNC v3.9.8 (wifi) '$' for help]
> $HOSTNAME
$Hostname=fluidnc
ok
> $HOSTNAME=aaa
ok
> $HOSTNAME    
$Hostname=aaa
ok
> $HOSTNAME=bbb
ok
> $HOSTNAME    
$Hostname=aaabbb
ok
> $HOSTNAME=ccc
ok
> $HOSTNAME    
$Hostname=aaabbbccc
ok

if I set hostname/apssid (or whatever) multiple times without reboot, the first time is ok, then value is never correct, it becames “aaa + bbb + ccc”.
