[VSCode] Symbols list incomplete

[e-zz]

(Please refer to #2019 for my system specifications. Tested also on a linux machine.)

Hi
The symbols list panel in vscode (invoked by ctrl+shift+o or ctrl+p+@) is very often incomplete.
For example, a file test.typ has only one variable

#let c_bg = rgb("#fafafa")

We can see our only variable in the file c_bg

But with a commented line above the variable, like

//
#let c_bg = rgb("#fafafa")

The variable c_bg will be invisible in the symbol list
