When using the BETA via the button and then pressing settings, I get logged out, so I cant use the new dark mode :(

Maybe @mmso or someone else from the ProtonMail team can why we get outlogged when visiting Settings in beta?

I've digged a bit deeper into this, it seems to be related to that pagehide event isn't fired in the webview when the page reloads. https://github.com/ProtonMail/WebClient/blob/0912dff240dde923de91ed8c7d42e7ff3151259d/src/app/commons/services/secureSessionStorage.js#L21
