In addition to being a regression, this is failing payloads in multiple releases; see below.

Component Readiness has found a potential regression in the following test:

[sig-network][Feature:EgressFirewall] when using openshift ovn-kubernetes should ensure egressfirewall is created [Suite:openshift/conformance/parallel]

Significant regression detected.
Fishers Exact probability of a regression: 100.00%.
Test pass rate dropped from 100.00% to 94.59%.

Just the test details should be enough to motivate some action on this, but TRT also notes that this has been failing payloads.

We first noticed it in 4.19.0-0.nightly-2025-03-03-234514

It's been failing sporadically since then, usually not enough to fail aggregated jobs on payloads, but recently we've also seen it in 4.19.0-0.ci-2025-03-05-040239 and 4.18.0-0.ci-2025-03-04-090104 so we consider this a payload blocker.
