1806413 - Schedule pre-loaded scripts for execution

Status: RESOLVED FIXED

(Remote Protocol :: WebDriver BiDi, task, P1)

Description

[Henrik Skupin [:whimboo][⌚️UTC+2]]

Before we can add basic support for pre-loaded scripts our BiDi implementation needs the ability to schedule custom scripts for evaluation while the page is loading.

How the execution needs to happen will be added by the following PR for the html spec:
https://github.com/whatwg/html/pull/8300

The document parser can be blocked by calling document.blockParsing, which would allow us to evaluate all the registered scripts. Requirement here is that this needs to happen as early as the document has been created. Therefore we need to observe "document-element-inserted".

An example can be found at:
