The encodeURL (renamed to ensureEncoded and exposed in this commit) already
handled already-encoded URLs, so this was largely a matter of exposing the
functionality.
The reason this isn't baked directly into Page.navigate is that, in some places
e.g. internal navigation, the URL is already know to be encoded. So it's up
to every caller to make sure they are passing a valid URL to navigate.
This is normally not called in "normal" dump-usage, but with
XMLSerializer.serializeToString an Attr node _can_ be provided. The spec says,
and FF agrees, this should return an empty string.
When set (defaults to not set/false), --dump will include iframe contents.
I was hoping I could add a mode to strip_mode to this, but since dump is used
extensively (e.g. innerHTML), this is something that has to be off by default
(for correctness).

We previously ran the message loop every 250ms. This commit changes it to run on
every tick (much more frequently). It also runs microtasks after draining the
message loop (since it can generate microtasks).
Also, we use to run microtasks after each script execution. Now we drain the
message Loop + microtasks.
We still only drain the microtasks when executing v8 callbacks.
As part of this change, we also adjust our wait time based on whether or not
there are pending background tasks in v8 in order to try to execute them (in
general) and in a timely manner.
The goal is to ensure that tasks v8 enqueued on the foreground thread are
executed promptly.
This change is particularly useful for calls to webassembly as compilation
happens in the background and eventually requires the message loop to be drained
to continue.
Previously, if a script did `await WebAssembly.instantiate(....)`, there was
a good chance we'd never finish the code - we'd wait too long to run the
message loop AND, after running it, we wouldn't necessarily resolve the promise.
Some CDP clients (e.g. playwright-go) request /json/version/ with a
trailing
slash. Added handling for this variant to match the exact same behavior
as /json/version
Given:
a.href = "over 9000!"
Then:
a.href === BASE_URL + '/over%209000!';
This commits adds an escape: bool option to URL.resolve which will escape the
path, query and fragment when true.
Also changes the Anchor, Image, Link and IFrame getSrc to escape. Escaping is
also used when navigating a frame.
We currently store all of the env's contexts in an ArrayList. When performing
micro/macro tasks, we iterate through this list and perform the micro/macro
tasks. This can result in the ArrayList being invalidated (e.g. a microtask can
result in a context being created, a promise resolving and creating an iframe).
Invalidating the arrylist while we iterate through it is a use-after-free.
This commit stores contexts in a fixed array (64) so that it doesn't move.
Iteration is slower, unfortunately, as the new `env.context_count` has to be
checked.

This commit also prevents microtasks execution from causing microtask execution.
On the above test, I saw runMicrotasks which I don't think we're supposed to do.
