"Ctrl + Shift + character" binds not working properly?

[Opposite34]

2. Issues with the Zellij UI / behavior / crash

Issue description

I read the documentation, and saw that only "modifier + character" is allowed. However, I was still confused on whether or not "Ctrl Shift" modifier was supported as a whole. I asked around and was suggested to try clear the default and test it out, but it doesn't seem to work at the moment?

keybinds clear-defaults=true {
   normal {
       bind "Ctrl T" { NewTab; }
   } 
}

I also tried "Ctrl Shift t" but that's just straight up shows invalid.

Minimal reproduction

Using minimal keybind configs above as to try to bind "Ctrl Shift t" to new tab, which doesn't work.

Other relevant information

Currently on version 0.40.1, I can confirm that if I just bind "Ctrl t" for above it works. I'm currently using foot for the terminal in replacement of kitty because it takes 2-3 second to startup (hence my reason on using Zellij, as I want tabs in my terminal, and if possible I want to rebind them to how kitty does it).
