Select-kit חסר לחלוטין

[Don]

Hello,

I think the problem is the backdrop-filter is not working well on nested elements.
I suggest to remove backdrop-filter from these elements or try to add it to a ::before pseudo.

Something like this
This is just an example for composer. You have to change it to the other elements you use it.

#reply-control.open,
.d-editor-textarea-wrapper {
    background-color: rgba(var(--header_background-rgb), 0.15);
    &::before {
      content: '';
      position: absolute;
      width: 100%;
      height: 100%;
      -webkit-backdrop-filter: blur(2rem);
      backdrop-filter: blur(2rem);      
      z-index: -1;
    }
  }

And it looks like this with working select-kit.
