Allowlist cwd/resources in the default WebKit context before any web process starts, force software rendering defaults, drain host stdout from the launcher, and run Linux CI under dbus-run-session + soft-GL env. Co-authored-by: Dominic Letz <dominicletz@users.noreply.github.com>
Disable the WebKit process sandbox when --edw-test-rpc is set, and load fixture HTML via data: URLs so E2E does not depend on bubblewrap file maps. Co-authored-by: Dominic Letz <dominicletz@users.noreply.github.com>
