Patch Changes

• #3544 d120042 Thanks @ksvat! - fix: stop session recording before destroying sessionManager in opt_out_capturing() with cookieless_mode: "on_reject". Previously, queued/throttled rrweb events (e.g. mousemove) could fire after the sessionManager was set to undefined and throw [SessionRecording] must be started with a valid sessionManager. Also adds a defensive early-return in onRRwebEmit so any remaining late events bail out instead of throwing.

• #3542 94a5ba0 Thanks @TueHaulund! - Preserve <style> textContent when the browser's CSSOM serialization would
  emit empty longhands from var() inside a shorthand. When a stylesheet has
  e.g. padding: var(--p); padding-bottom: var(--pb);, browsers store the
  shorthand's longhands with empty token lists per the CSS Custom Properties
  spec, and CSSStyleRule.cssText re-emits them as padding-top: ; padding-right: ; padding-left: ;. The previous behavior replaced the
  <style> text with that corrupted output, silently dropping layout rules
  on replay. We now detect the empty-longhand pattern and keep the original
  textContent in that case. Affects users of any CSS-in-JS framework that
  combines var() with shorthands (Chakra UI v3, Panda CSS, Emotion, etc.).
  Same class of bug as rrweb-io/rrweb#1667. (2026-05-07)
