This was introduced in #7500 to fight `ERROR: The process "4436" not found.`
messages when killing a process that did already exit.
Since then, we no longer inherit stdout/stderr, so the error message
should not appear anymore.
This is a speculative fix to leftover tmp directories.
When users issues SIGINT twice, we enter `gracefullyClose()`
twice, and shortcut the second time. It turns out, we do
not wait for directories removal.
Note: it is unknown how often we reach this codepath in practice.
Previously, we were guessing whether something is optional from the
comment (looking for stuff like "defaults to" or "optional").
To remove this error-prone technique, every optional property or
argument (but not option) is explicitly marked with "?".
- This supports `role=button[name=Hello]` similarly to CSS selectors.
- Does not change `_react` or `_vue` behavior that insist on quoting the string.
- Uses CSS notion of "identifier" characters.
This patch will check if browser channel is already installed.
If it is, it'll abort installation with the following error:
```
aslushnikov:~/prog/playwright$ npx playwright install msedge
Failed to install browsers
Error:
╔═════════════════════════════════════════════════════════════════╗
║ ATTENTION: "msedge" is already installed on the system! ║
║ ║
║ "msedge" installation is not hermetic; installing newer version ║
║ requires *removal* of a current installation first. ║
║ ║
║ To *uninstall* current version and re-install latest "msedge": ║
║ ║
║ - Close all running instances of "msedge", if any ║

Fixes https://github.com/microsoft/playwright/issues/13061
It turns out that "non stalling evaluate" can stall in Chromium
in some weird conditions, like `document.open` after some weird
`iframe.src` value.
We now only hide highlight in those frames where we did install
highlight in the first place.
