Justin Halsall 80e7307729 Tests: Iframe event order (#568)
* add failing test

* assert order of events

* defer attaching of iframe till FullSnapshot is done
Fixes: https://github.com/rrweb-io/rrweb/issues/567

* correct event order in iframe integration test snapshot

* trigger build

* trigger build

* Move settimeout responsibility to snapshot
https://github.com/rrweb-io/rrweb-snapshot/pull/78

* upgrade rrweb-snapshot to 1.1.4

* DRY record tests

* cleanup

* Upgrade puppeteer to 9.1.1
for (hopefully) more consistent behaviour between CI and development

* make input bigger to prevent triggering scroll events

* page.waitFor is deprecated
more info: https://github.com/puppeteer/puppeteer/issues/6214

* Set os and distro for Travis ci
