Toggle Line Comment not working for Verilog Filelist?

[musketon-be]

Hello,

I have some files defined as 'Verilog Filelist'. I see that the syntax highlighting is in place, e.g. lines with '//' are indicated as comments.
However, when I do 'Edit -> Toggle Line Comment' (or ctrl+/), then nothing happens.
When editing Verilog/SystemVerilog files, then this works.

Something wrong/missing in the extension maybe?
