There was a problem hiding this comment.
Looks good to me, at least as a temporary measure until we have more idea about what's happening!

A lot of tests are timing out when they call
page.waitForLoadState( 'networkidle' ). @talldan rangit bisectand worked out that it's to do with a recent Core commit that adjusted theCache-Controlheaders set by WordPress. Removingno-storefrom the header seems to fix the issue.I'm pretty stumped as to why this happens. (A Chrome bug?) This PR simply uses the
nocache_headersfilter to removeno-storefromCache-Controlheader in our E2E test environment. Hopefully this fixes the tests and unblocks committers from doing work while we investigate what's actually going on here.Related Trac ticket: https://core.trac.wordpress.org/ticket/58592
