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.

After API review we decided to revert it:
* VSCode extension and UI mode users already get the (runtime) error if
the tag is not prefixed
* The typescript error message is not very nice
* The type change would break those clients that generate tests with
tags passed as string
This reverts commit 90e7b9ebacbd597b7380522001eb6d17ee9c3d86.
Closes https://github.com/microsoft/playwright/issues/32076.
This PR rewrites `watchMode.ts` to use `TestServer` under the hood. It's
essentially a complete rewrite, so don't pay too much attention on the
old implementation. Note that there's no changes to tests, so all
behaviour we have specced out there still works.
To make this work without a superfluous WebSocket connection, I had to
refactor `TestServerConnection` a little. Originally, I pulled this into
a [separate PR](https://github.com/microsoft/playwright/pull/32132), but
then realised how small the refactoring is. So it's in this PR now. Let
me know if you'd like to land it separately.
The `'should support custom matchers'` test asserts that the
functionality works, but it was a type error. This PR updates the types
so that it's allowed.

Our CI operates on shallow clones. In vcs.ts, we perform a check for
shallow clones in `process.cwd()` instead of the test directory. This
makes the test in
3c208aeeff/tests/playwright-test/only-changed.spec.ts (L201)
failing in CI, but only for PRs. The fix is to perform the check on. the
test directory.
Closes https://github.com/microsoft/playwright/issues/32331
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/32256
We were expecting all errors to be of type `ExpectError`, but apparently
`expect` propagates rejections in the polling functions right through.
So we also need to handle that case.
I wonder if we have more cases of this. Would it make sense to enable
`useUnknownInCatchVariables` in TypeScript?
