Sorry for missing this bug!
Not sure how this CL could have any impact on desktop memory, as the feature (firing the page lifecycle callback) was not even enabled on desktop and was behind another flag on mobile.
So I believe this is the wrong culprit.

I think we can close this out given the graph has recovered.
