Code leaked cacheability metadata

I just started coming across this problem as of 3.10. It pops up when using a link with the 'destination' parameter, as in this twig template snippet:
<a href="/saml/login?destination={{ path('<current>') }}">Website Login</a>

With 📌 Exception in EarlyRenderingControllerWrapperSubscriber is a DX nightmare, remove it Needs work maybe this isn't a problem anymore? Or rather, the problem is no longer an exception?

Embarrassingly, 3.x-1.10 itself contains an error that triggered the warning and therefore should be fixed. Your issue is probably fixed with 🐛 Cacheability Metadata Leakage Error on SAML Login with Samlauth and r4032 Redirect Module Active . 8.x-3.11 is out now.
