After logging in via maintenance login form, can't logout

[Karmalakas]

Steps to reproduce

• Fresh Core + Admin install (at the time of writing, 1.7.5)
• Go to page, create user, update Login (it's 3.3.8 there instead of 3.4.0)
• Make any page accessible only with site.login
• Navigate however you want - login/logout works just fine
• Install Maintenance plugin
• Enable maintenance mode
• Go to any page
• Login (even with same admin user)
• Logout won't work anymore - will give

Forbidden
You don't have permission to access /task:login.logout/logout-nonce:xxx on this server.

So basically, if I login through Maintenance login form, I can't logout due to that error, but if I login through default login form on some restricted access page, then I can logout without a problem.

Could it be something with maintenance.md form config?

form:
    name: login
    action:
    method: post
    login:
        forgot_button: false

    fields:
        - name: username
          type: text
          placeholder: PLUGIN_LOGIN.USERNAME
          label: PLUGIN_LOGIN.USERNAME
          autofocus: true

        - name: password
          type: password
          placeholder: PLUGIN_LOGIN.PASSWORD
          label: PLUGIN_LOGIN.PASSWORD

Although I don't see anything special
