what's the fix version for this?

mcollina · Feb 10, 2026

@aduh95 why did you mark this as semver-major? This was on purpose a fix.

Causes conflicts with localStorage during the vitest tests with jsdom. This should get fixed in node.js 26 So i think it's fine if we leave this in CI only. Node.js 26 isn't too far away. nodejs/node#61333 nodejs/node#60303 Signed-off-by: Jannik Hollenbach <jannik.hollenbach@owasp.org>
