Autocomplete for variables not working

[skorphil]

Hi, it seems like there is no suggestions for variables.

I had variables:

@startuml
!$var_1 = ' variable 1 example '
!$var_2 = ' variable 2 example '
...

I'm trying to use defined variables, but there is no suggest(autocomplete).

$| (Expected suggest var_1, var_2)

Same with procedures

!procedure $procedure($input)

$p| (nothing happened here)
