The error looks like this:

Fixes#17699
This makes `HttpServer` accept `preferredPort` option that will first
try to listen on that port, and if that port is already in use, listen
on some available port instead.
Fixes#17201.
Element.checkVisibility is a new browser API that was shipped in
chromium 105:
https://bugs.chromium.org/p/chromium/issues/detail?id=1309533
Using checkVisibility accounts for the content-visibility:hidden in the
user-agent ShadowRoot of the details element, which means we can remove
the usage of the AutoExpandDetailsElementFlag (I am trying to remove the
flag in chromium).
This behavior is covered by the existing "isVisible and isHidden should
work with details" test in locator-convenience.spec.ts.
This patch introduces hidden commands to control container
lifecycle:
- `npx playwright docker install-server-deps` to install fluxbox,
vnc, novnc & to configure them.
- `npx playwright docker run-server` to run a server inside the
container.
Drive-by: remove old version of container image when building a new
version with the same name. This way we won't pile up untagged
container images.
Currently, we ues `#root` vs `#root > *` selector for component roots
depending on the number of root children. This heuristic detects
fragments that render multiple elements inside the root.
However, this does not work with empty fragments that do not render
anything.
The fix is to make the `#root >> control=component` selector that would
dynamically detect the root. This supports empty fragments and also
allows for dynamic updates of the fragments.
Often times we see "Browser has been closed" error, but it's not
entirely clear why. Showing the close stack might help.

This patch introduces the following commands:
- `npx playwright docker build` that builds a VRT docker image
locally that is based off the `mcr.microsoft.com/playwright:jammy`
- `npx playwright docker start` that launches a docker container with
browsers.
- `npx playwright docker stop` that stops given docker container.
- `npx playwright docker test` that runs all the tests inside a
launched docker container.
