It's not hard to add one line of context so readers aren't lost. Here, take this for example, combining a couple parts of the GitHub readme:
> For those who are unfamiliar, the Sanitizer API is a proposed new browser API being incubated in the Sanitizer API WICG, with the goal of bringing this to the WHATWG.
Easy. Can fit that in right after "this blog post will explain why", and now everyone is on the same page.
