Bumps postcss-selector-parser and stylelint-browser-compat. These dependencies needed to be updated together.
Updates postcss-selector-parser from 6.1.4 to 7.1.7

Release notes

Sourced from postcss-selector-parser's releases.

7.1.7

  • fix: lossless: true preserves trailing whitespace in a selector that ends empty, such as :not(a, ). Note that :not( ) now yields a selector holding one empty string node rather than an empty selector (#337 by @​theRizwan)
  • fix: consume the whitespace that terminates a hexadecimal escape, so [x="\000061 b"] unescapes to ab (#340 by @​jakezwang)
  • fix: set the parent on every node passed to insertBefore and insertAfter, not only the first (#343 by @​feritcemkahraman)
  • fix: assigning combinator.value clears the stale raw spelling instead of being ignored (#342 by @​SAY-5)
  • fix: keep whitespace around the namespace separator in attribute selectors, so [ foo | bar ] round-trips (#339 by @​dkryaklin)

7.1.6

  • fix: parse flat selectors in linear time, closing a CPU exhaustion vulnerability (GHSA-rj75-hqrm-r3gf, reported by Wayde Shi)

7.1.5

  • fix: don't treat a non-prefix token before | as a namespace (#324 by @​spokodev)
  • fix: preserve whitespace before a * namespace in attribute selectors (#325 by @​spokodev)
  • fix: TypeError on unclosed [, ( and trailing | (#330 by @​theRizwan)

7.1.4

  • fix: tolerate non-node children when serializing selectors

7.1.3

  • Improve fix CVE-2026-9358 (NVD) / SNYK-JS-POSTCSSSELECTORPARSER-16873882 (clone/walk)

7.1.2

v7.1.1

7.1.1

  • perf: replace startsWith with strict equality (#308)
  • fix(types): add walkUniversal declaration (#311)

v7.1.0

7.1.0

  • feat: insert(Before|After) support multiple new node

v7.0.0

7.0.0

  • Feat: make insertions during iteration safe (major)

6.1.5

The 6.x line is now in security-only maintenance

This release exists because the advisory above covers every published 6.x version, and until now the only remediation on offer was an upgrade to 7.x. 6.1.5 is the patched version for the 6.x line.

The line is kept alive for the installed base that cannot move to 7 yet, Tailwind
