simulator parse error on library file

Description

Assigning library with line

.MODEL DVNF D KF={PWR(FLWF,0.5)/1E11} IS=1.0E-16

to schematic symbol rises error "expected newline not following by a line continuation" while rewriting this line to

.PARAM kf_={PWR(FLWF,0.5)/1E11}
.MODEL DVN D KF={kf_} IS=1.0E-16

seems to be parsed correctly

Steps to reproduce

1. Open schematic, place symbol, open simulation parameters
2. Try to assign library containitg following code:

.SUBCKT FEMT_INV 1 2 
.PARAM NLFF = 100000 
.PARAM FLWF = 100
.PARAM NVRF = 20000
.PARAM GLFF={PWR(FLWF,0.25)*NLFF/1164}
.PARAM RNVF={1.184*PWR(NVRF,2)}
.MODEL DVNF D KF={PWR(FLWF,0.5)/1E11} IS=1.0E-16
