question - lazyload example

[dan-ding]

is the lazy load example script: https://github.com/GoogleChromeLabs/puppeteer-examples/blob/master/lazyimages_without_scroll_events.js supposed provide an accurate "view" of what the googlebot (image or search) sees -- visually and dom-wise?

Many lazyloading scripts try to compensate by sniffing the UA (including the included example). However it's not clear if the result of the dom manipulation (say swapping data-src to src) is indeed what the google grabs.

I understand it's chrome, not the google - but do you have any insight or knowledge of how we should interpret the results to what the google sees? Or this just a test of the events and not indicative of the googles view?

It (purposefully?) does not set the UA to a googlebot, so I'm guessing there's an interpretation we should be taking away from it.
