Since browsers are launched through a redirect.html file (#2703), the
test tab starts on a file:// URL and only reports the test URL once
the navigation commits. _connect, used with --debug and
--coverage, gave up after about 4 seconds, which is not always enough
on loaded CI runners. The Chrome coverage tests have failed with "Could
not connect to test tab" on Windows and macOS since that change landed.

Poll for up to about 20 seconds, and include the URLs of the open tabs
in the error to make any future failures easier to diagnose.

Since browsers are launched through a `redirect.html` file (#2703), the

on loaded CI runners. The Chrome coverage tests have failed with "Could
not connect to test tab" on Windows and macOS since that change landed.
