* fix(replay): preserve <style> textContent on var-shorthand CSS
When a CSS rule combines a shorthand with var() and a longhand override,
e.g.
.card { 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: ; padding-bottom: var(--pb);
The previous serializeTextNode path replaced the original <style> text
with that corrupted output, silently stripping layout rules on replay.
Affected users of any CSS-in-JS framework that combines var() with
shorthands -- Chakra UI v3, Panda CSS, Emotion -- where the form card
padding, flex centering, grid track sizing etc. would vanish in playback
while colors and other single-property declarations stayed intact.
Detect the empty-longhand pattern in stringifyStylesheet's output and
keep the original textContent in that case. Custom properties
(--foo: ;) are intentionally excluded since they may legitimately be
empty.
See rrweb-io/rrweb#1626 / #1567 for the upstream issue tracking.
* chore: correct upstream issue reference (rrweb-io/rrweb#1667)
* fix(replay): also detect vendor-prefixed empty longhands
* test(replay): real-browser playwright coverage for var-shorthand <style> fix
Adds a Chromium + Firefox Playwright spec that exercises the
stringifyStylesheet -> rule.cssText round-trip in a real browser, which
jsdom cannot reproduce. The spec covers:
1. @layer block + atomic utilities + nested @media round-trip cleanly
(regression guard for grouping at-rules).
2. shorthand-with-var() plus a longhand override (the customer's
reported pattern at app.sonia.so/login) does not surface empty
placeholder longhands in the captured <style> textContent.
3. <style> with seeded text plus a runtime sheet.insertRule() addition
captures both rules when the round-trip is clean (regression check
for the corruption-detection branch — must not over-fire).
Also adds two playgrounds under packages/browser/playground/:
- css-layers/ Synthetic fixture for the playwright spec above.
Drives all three test cases via document.styleSheets API and
textContent.
- chakra-emotion/ Vite + React + Chakra UI v3 + @emotion/react +
posthog-js (linked) playground that mirrors the customer's stack.
Useful as a debugging artifact for future CSS-in-JS replay issues;
not currently driven by automated tests.
