Border option doesn't do anything

[C8H9NO2-1]

When I try to change the colour and the width of the border with the following option, it doesn't change anything compared to the default config.

"border": {
    "width": 5,
    "color": "#5e81acff"
},

• With the default config (codesnap -f main.c -o clipboard):

• With the change to the border option (codesnap -f main.c -o clipboard):

• Using CodeSnap.nvim, I can achieve the desired result:

I also tested it with png, svg and html outputs and all seem to have the same issue
