Using the `call_arena` here is unsafe in the case of a failure. It's possible
for the call_arena to be reset during module processing, making the log crash.
The issue is that the lifetime of a URL is often conditional. If the stitched
URL has already been seen (i.e. is in the module_cache), then it can be short-
lived. EXCEPT, URL.stitch might require an allocation..and then you start to
think, well, if URL.stitch is going to allocate anyways...If we stitch with
the `page.arena`, and end up not needing a long lifetime, we've wasted memory.
If we stitch with `page.call_arena` and end up needing a long lifetime, we need
to dupe.
It's a bit messy, and I'd like to take a stab at improving it after:
https://github.com/lightpanda-io/browser/pull/1127.
I'm thinking that we need a URL intern pool. HashMap with a composite key of
base + path -> resolved. Then all URLs are resolved using the page.arena, but
we don't have any duplicates, so it isn't wasteful.
In their current implementation, both the NodeIterator and TreeWalker would
skip over ignored nodes. However, while the node itself should have been ignored
its children should still be iterated.
For example, when going over:
```
<div id="container">
<!-- comment1 -->
<span>
<!-- comment2 -->
</span>
</div>
```
With `SHOW_COMMENT`, the previous version would completely skip over `container`
and its children. Now the code still won't emit the `container` div itself,
it will still iterate through its children (and thus emit the two comments).
This change relates to ongoing react compatibility.
This is how, for example, scripts on lightpanda.io are. Though fixing this
doesn't really change anything, it's good to make sure these events are firing
correctly.
First, this exposes the v8 Profiler. Right now it's just a commented-out block
in `fetch` and meant for internal debugging.
Depends on: https://github.com/lightpanda-io/zig-v8-fork/pull/105
Use postAttach on Window to attach "static" properties. This comes from
profiling (lightpanda.io) and seeing window.get_self called tens of thousands
of times.
