}Describe your issue
when porting the pattern above from Tailwind v3, i noticed that the Tailwind language server became caught in what appears to be an infinite loop.
building (with postcss) still succeeds, and does not consume excessive resources.
the same behavior does not occur when using a different, non-shadowed, variable name.
@theme {
--color-label: rgb(from var(---color-label) r g b);
}
@utility color-scheme-light {
---color-label: black;
}
@utility color-scheme-dark {
---color-label: white;
}if my assumption is correct, and the name shadowing is the root cause here, i would not mind if shadowing was flagged as an error.
