Trace snapshots are a best-effort snapshots of the browser DOM, but we
can't guarantee them to be exactly what the browser showed. One example
of this is `canvas` elements, where you just can't see their contents.
That makes snapshots useful, but not perfect.
For those cases where the snapshot doesn't show everything, this PR
introduces a new setting to show a screenshot instead. You won't be able
to scroll or inspect the DOM or select a locator anymore. But if the
snapshot was missing something, or displaying something wrong, you can
now check the screenshot instead.
In the `visit` method, we currently cache the rendered HTML for every
walked node. This re-use works well for traces that consist mostly of
references to earlier snapshots.
But for traces that don't share much, this is a large memory overhead
and leads to the memory crash documented in
https://github.com/microsoft/playwright/issues/32336. For the algocracks
amongst you, the current memory usage for an html tree $h$ is
$\mathcal{O}(|h| * \text{height}(h))$.
This PR removes that cache from the nodes and replaces it with a
snapshot-level cache, fixing the memory crash.
Traces *without* reference should not see a performance impact from
this.
Traces *with* references will have slower initial rendering, but
re-rendering maintains speed because of the snapshot-level cache.

We're already passing the `outputDir` param to the UI, but the UI isn't
passing it back to the TestServer. This PR fixes that. I've added it to
`listTests`, which is requires to that
`TestServerDispatcher#_ignoredProjectOutputs` is populated with the
correct output dir. And i've added it to `runGlobalSetup`, which is what
the bug report was about.
Closes https://github.com/microsoft/playwright/issues/32159. I
originally set out to enable Strict Mode for our React UI, but found a
way better thing: Enabling the lint rules we had already installed!
`eslint-plugin-react` is already in of our `package.json`, and this PR
enables it and fixes some of the reported issues. Most of them are
around the `key` prop which is mostly about performance, but there's
also fixes for misspelled `data-testid` props.
`x-unknown` is used as a placeholder for "no content-type" in the har.
We should not send it to the browser, because it is meaningfully
different from not sending `Content-Type` header. For example, Chromium
refuses to interpret stylesheets served with `x-unknown` content type.
Fixes https://github.com/microsoft/playwright-java/issues/1651.

When keyboarding through the action view, the UI continues showing the
hovered action. This makes keyboard nav hard to use.
The fix is to reset the higlighted action on keyboard navigation. This
is what we do when the mouse pointer leaves an action, and what I think
is reasonable.
* Hide 'Status Code:' field for interrupted requests that don't have it.
* Clear up previously selected body when showing aborted requests.
* Highlight interrupted requests in red.
When two attachments have the same content sha1, we used the first one's
name for the downloaded file, no matter which one the user clicked to
download. Now we pass the name explicitly.

I stumbled over `React.Children`, because it's the first time I saw that
used. https://react.dev/reference/react/Children lists `React.Children`
it as "Legacy" and mentions it's uncommon. Also, the fact that SplitView
only displays its first two children, and all others are silently
discarded, can be a surprise to some.
By separating things out into `sidebar` and `main`, not only do we give
the two elements names (otherwise one needs to remember that sidebar is
always the first child), but we also prevent any "third children" from
being dropped.
Addresses https://github.com/microsoft/playwright/issues/31863. This PR
is chonky, but the individual commits should be easy to review. If
they're not, i'm happy to break them out into individual PRs.
There's two main things this does:
1. Remove some unused imports
2. Add a `clsx`-inspired helper function for classname templating
I wasn't able to replace `ReactDOM.render` with `ReactDOM.createRoot`.
This is the new recommended way starting with React 18, and the existing
one is going to be deprecated at some point. But it somehow breaks our
tests, i'll have to investigate that separately.
