* test(recording side): add test case for adopted stylesheets in shadow doms and iframe * add type definition for adopted StyleSheets * create a StyleSheet Mirror * enable to record the outermost document's adoptedStyleSheet * enable to serialize all stylesheets in documents (iframe) and shadow roots * enable to record adopted stylesheets while building full snapshot * test: add test case for mutations on adoptedStyleSheets * defer to record adoptedStyleSheets to avoid create events before full snapshot * feat: enable to track the mutation of AdoptedStyleSheets * Merge branch 'fix-shadowdom-record' into construct-style * fix: incorrect id conditional judgement * test: add a test case for replaying side * tweak the style mirror for replayer * feat: enable to replay adoptedStyleSheet events * fix: rule index wasn't recorded when serializing the adoptedStyleSheets * add test case for mutation of stylesheet objects and add support for replace & replaceSync * refactor: improve the code quality * feat: monkey patch adoptedStyleSheet API to track its modification * feat: add support for checkouting fullsnapshot * CI: fix failed type checks * test: add test case for nested shadow doms and iframe elements * feat: add support for adoptedStyleSheets in VirtualDom mode * style: format files * test: improve the robustness of the test case * CI: fix an eslint error * test: improve the robustness of the test case * fix: adoptedStyleSheets not applied in fast-forward mode (virtual dom optimization not used) * refactor the data structure of adoptedStyleSheet event to make it more efficient and robust * improve the robustness in the live mode In the live mode where events are transferred over network without strict order guarantee, some newer events are applied before some old events and adopted stylesheets may haven't been created. Added a retry mechanism to solve this problem. * apply Yanzhen's review suggestion * update action name * test: make the test case more robust for travis CI * Update packages/rrweb/src/record/constructableStyleSheets.d.ts Co-authored-by: Justin Halsall <Juice10@users.noreply.github.com> * Update packages/rrweb/src/record/constructableStyleSheets.d.ts Co-authored-by: Justin Halsall <Juice10@users.noreply.github.com> * apply Justin's review suggestions add more browser compatibility checks * add eslint-plugin-compat and config * fix record test type errors * make Mirror's replace function act the same with the original one when there's no existed node to replace * test: increase the robustness of test cases * remove eslint disable in favor of feature detection Early returns aren't supported yet unfortunately, otherwise this code would be cleaner https://github.com/amilajack/eslint-plugin-compat/issues/523 * Remove eslint-disable-next-line compat/compat * Standardize browserslist and remove lint exceptions (#1010) * test: revert deleting virtual style tests and rewrite them to fit the current code base Co-authored-by: Justin Halsall <Juice10@users.noreply.github.com>
