Explore options for resolving {T416405} which include
* Making lead paragraph work on non-Parsoid views
* Use Parsoid for all page views in experiment
* Approach the experiment differently. Do not disable SectionTransform via `$wgMFNamespacesWithoutCollapsibleSections` and instead disable the associated JavaScript.
Outcome:
[X] We have decided a strategy for ensuring the control and treatment group are consistent with the only difference being the floating table of contents in the treatment group.
* (jon and brooke agreed that while it sorta works to hack up the transforms, it's potentially risky to non-experiment code. conservative approach is to go ahead and switch the control and transform groups to both use parsoid, which is a known quantity)
[X] We can estimate {T416405}
* (i'm putting it at a 2)
