## After
* Helpful error message if docker isn't running
* Doesn't crash when local-only images in list
* No typo in `playwright install docker-image` command
* When other playwright images are found they are listed and `PW_TEST_IMAGE` is mentioned
### After: Docker not running

When configuring a proxy, Chromium requires a magic tokens to get some
local network requests to go through the proxy. This has tripped up a
few users, so we make the behavior default to the expected: proxy
everything including the local requests. This matches the other vendors
as well.
NB: This can be disabled via
`PLAYWRIGHT_DISABLE_FORCED_CHROMIUM_PROXIED_LOOPBACK=1`
Supercedes: #8345Fixes: #10631
There were two issues:
- we did not find VDom roots inside shadow DOM
- we incorrectly relied on DOM's `contain` method to determine if
VDom's rendered node belongs to requested scope.
Fixes#10123
Sometimes we get "Network.webSocketWillSendHandshakeRequest" in Chromium.
Perhaps websocket is restarted because of chrome.webRequest extensions api?
Or maybe the handshake response was a redirect?
This reports websocket twice and triggers an assert.
Consider the following scenario:
- Tracing is started.
- API call is made (e.g. page.waitForResponse), almost finishes, and
enters onAfterCall where it starts a snapshot.
- tracing.stopChunk is called, and waits for existing actions to finish.
However, it does so by calling onAfterCall one more time.
- tracing.stopChunk removes instrumentation listener and returns
to the client.
- Client starts zipping files.
- Original API call finishes the snapshot and saves it to the trace file.
This results in trace file being written to while the zip is still working.
Makes it easier to understand that expect does indeed have a separate timeout.
```
Error: expect(received).toHaveCount(expected) // deep equality
Expected: 0
Received: 1
Call log:
- expect.toHaveCount with timeout 500ms
- waiting for selector "span"
- selector resolved to 1 element
- unexpected value "1"
- selector resolved to 1 element
- unexpected value "1"
- selector resolved to 1 element
- unexpected value "1"
```
Turns out we were using wrong formula; with the config we had in place,
proper-lock-file would give up to aquire lock after 49 seconds of
waiting.
With the proper configuration, we'll keep re-trying for 10 minutes.
Fixes#10354
