In #45737 we've introduced a potential optimization to the performance job, the problem is that it resulted in the job comparing the wrong thing.

Basically if a branch was equivalent to the "test branch", we reused the same code to gain some time and avoid the git clone, the issue is that we didn't build the code in that case, meaning we were using the WP trunk version of Gutenberg and not the actual branch.

(Currently WP trunk's version does have the '/navigation/single' support in the site editor which explains why this random change fixed the perf job.

The bummer is that you can say that for the last three months, the perf jobs in PRs were useless.

That also explains why I was completely unable to repro locally. 💥
Nice catch, though the bug is indeed a nasty one! 🐛

The change is not necessary but I think it's a bit safer than the previous code, so I decided to leave it.

await page.waitForSelector(
'.edit-site-visual-editor__editor-canvas[role="button"]',
{ timeout: 3000 }
);

await canvas().click( 'body' );
} catch {
// This catch is necessary for the performance tests in old branches
// where the site editor toggle was not implemented yet.
}
await canvas().click( 'body' );
