v2.11.2

Patch Changes

• #251 0cbd809 Thanks @tenphi! - Fix injected styles never being removed in text-injection mode, so useGlobalStyles layered new CSS on top of old CSS instead of replacing it.

  SheetManager inserted rules two ways — CSSOM, or by appending to <style>.textContent — but only ever deleted through CSSOM. In text mode (auto-enabled in test environments, configure({ forceTextInjection: true }), and the fallback whenever styleElement.sheet is unavailable) every dispose() was a silent no-op against the text, so updating a slot appended another copy of the rules while the stale ones kept matching the selector:

  useGlobalStyles(':root', { fill: '#red' },   { id: 'theme' })
  useGlobalStyles(':root', { fill: '#blue' },  { id: 'theme' })
  useGlobalStyles(':root', { fill: '#green' }, { id: 'theme' })
  
  // before: three :root rules stacked      after: one :root rule, green
  

  Rule texts are now tracked per sheet in text mode and the element is rebuilt on delete, mirroring how raw CSS already worked. This also makes ref-counted cleanup and GC effective in text mode.

  Also fixed in the same class of bug:

  • useGlobalStyles now clears its slot when the new styles render no CSS (previously {} left the old rules applied), and its slots are keyed per root, so the same selector in two shadow roots no longer evicts the other's rules.
  • useKeyframes disposed nothing when a named slot's steps changed, leaking an @keyframes rule per change and minting pulse-tk0, pulse-tk1, … instead of reusing the name. A named slot now holds one injection and keeps its name stable.
  • The client caches behind useGlobalStyles, useRawCSS, useKeyframes and useCounterStyle survived configure() replacing the global injector, so their change-detection keys suppressed re-injection into the new sheets and their dispose handles pointed at a dead injector. They are now keyed per injector and per root.
  • With an explicit id, useGlobalStyles and useRawCSS were last-write-wins on the client but first-write-wins in SSR/RSC, so an update inside one render pass shipped the old CSS. Slot-keyed entries now replace on the server too; content-hashed keys still only dedup.
