Runner._wait can iterate for the full opts.ms budget (up to 30s in
fetch, longer in agent tool-use loops). V8 was only nudged to GC on
session/page teardown (Browser.deinit, Page.deinit), so a page that
stays alive while running heavy JS accumulates wrappers and
external-ref'd Zig allocations V8 has no reason to drop. Fire
memoryPressureNotification(.moderate) once per second from the wait
loop.
Don't use pre-built snapshot for wpt action (the snapshot needs the WebDriver
added, which is not normally added). Instead, rely on runtime snapshot creation
(this just adds a bit of startup time and peak memory, neither or which should
be an issue for WPT runs).
Fired when elements are moved from one document to another. I don't think this
is really used much, but it helps pass a number of WPT cases.
This required tweaking insertAdjacentHTML as it was creating a full document
and trigger spurious callbacks in the new code. A DocumentFragment is now used
instead.
Support `new MyElement()` syntax to create custom element. The implementation
for this is pretty straightforward, but it depends on:
https://github.com/lightpanda-io/zig-v8-fork/pull/173.
Also modify the `attributeChangedCallback` and pass a missing parameter: the
namespace. Currently, we pass `null`, but this is less likely to cause issues
than not passing anything.
This possibly addresses some release overflows that could happen during various
failures. For example, if Frame.init fails during a navigation event, this will
make sure to remove the frame from the parent list preventing a double-free
on the frame.
functions should be defined directly on the window.console (and window.CSS)
instances. This is necessary for being able to iterate their "own" properties.
businessinsider.com has code that proxies console via such an iterator (through
Object.entries(console)). This commit allows types to declare that they own
their properties (as opposed to the prototype).
Also fixed HTMLDocument.location. This was using Document._location, but that
field wasn't always set. The new code removes the _location field and changes
the getter to get window._location. (Also an issue on businessinsider.com)
This API isn't supported by FireFox (yet), so it isn't a huge priority, but I
did notice that its used across many Google properties. It uses the same value
as Sec-Ch-Ua (https://github.com/lightpanda-io/browser/pull/2100) to provide
consistent data.
Smaller changes:
1 - Allow `OffscreenCanvas` to be used with Worker (noticed this error too)
2 - Don't like JS execution errors at "error" level for "load" and
"DOMContentLoaded". "error" should be reserved for things we can fix and
should never be triggered from invalid a bug in JavaScript.

This change is actually pretty mundane, but a bunch of files that used to
take a *Session (e.g. every WebAPI releaseRef and deinit) now take a *Page.
This aims to separate the 2 lifetimes currently managed by Session by moving
the "Page" lifetime to a dedicated container: Page. Ultimately, the goal is to
remove the 1-page-per-session limit of the current design. Not to explicitly
support multiple pages per session (though, that's more possible now), but
in order to better emulate Chrome where, during a navigation event, the old and
new page both exist.
