Originally we use Array.from to transform iterator into array.
But we found some framework may overwrite the Array.from with a
pollyfill which was not implement correctly.
* added our package
* reverted back to old rrweb snapshot
* Array.from does not capture all elements added in the set, we have to manually iterate through the iterator
* package lock
* added src set as a parsed attribute
* added tests
* changed to /a
* added multiple attribute handling
* added better comment
* made snapshot ignore invalid input as if it is invalid input in the original DOM, it should stay invalid in the recreated DOM
* added extra absolute test case
* code style
* addressed comments
In the case that the replayer triggers multiple FullSnapshot events, it
will call waitForStylesheetLoad multiple times. When the replayer
resumes, it could already have a timeoffset set from a previous
resume in a previous waitForStylesheetLoad call. In this case our new
timeoffset should be the value of our current time in the replay
(timer.timeOffset + getTimeOffset()). To solve this, I created a public
getCurrentTime function which correctly returns the time in the replay
and used that as our new timeoffset when resuming from a stylesheet
load.
Broken CSS inside a page will throw an error on our behalf. This should
be ignored because we are not in control of the CSS on the page we are
recording.
