Logical inline border generate useless CSS

[bakura10]

Hi :),

When using the following code:

.border-x {
  border-inline-width: 1px;
}

Parcel generates this:

.border-x:not(:lang(ae), :lang(ar), :lang(arc), :lang(bcc), :lang(bqi), :lang(ckb), :lang(dv), :lang(fa), :lang(glk), :lang(he), :lang(ku), :lang(mzn), :lang(nqo), :lang(pnb), :lang(ps), :lang(sd), :lang(ug), :lang(ur), :lang(yi)) {
  border-left-width: 1px;
  border-right-width: 1px;
}

.border-x:-webkit-any(:lang(ae), :lang(ar), :lang(arc), :lang(bcc), :lang(bqi), :lang(ckb), :lang(dv), :lang(fa), :lang(glk), :lang(he), :lang(ku), :lang(mzn), :lang(nqo), :lang(pnb), :lang(ps), :lang(sd), :lang(ug), :lang(ur), :lang(yi)) {
  border-left-width: 1px;
  border-right-width: 1px;
}

.border-x:is(:lang(ae), :lang(ar), :lang(arc), :lang(bcc), :lang(bqi), :lang(ckb), :lang(dv), :lang(fa), :lang(glk), :lang(he), :lang(ku), :lang(mzn), :lang(nqo), :lang(pnb), :lang(ps), :lang(sd), :lang(ug), :lang(ur), :lang(yi)) {
  border-left-width: 1px;
  border-right-width: 1px;
}

The expected result, because both left and right are setup, should be:

.border-x {
  border-left-width: 1px;
  border-right-width: 1px;
}

Thanks!
