Node is inaccessible when user schedules invalid transition

Problem/Motivation

As a user who isn't allowed to publish content via content moderation, I can schedule a publish state. Doing so, makes the node inaccessible as long as the "invalid" publish state is scheduled. Giving the Forbidden notice "Scheduled transition is not valid for the given account."
Why is the user able to schedule a publish transition (while not allowed to) and only afterwards the node is made inaccessible?

Steps to reproduce

1. Create a workflow publish transition
2. Create a user role which is not allowed the above publish transition
3. As a user with the above role, create content and and schedule it to publish in the future. Save the content.
4. As from now, the newly created content is inaccessible.

Proposed resolution

Don't make content inaccessible due to an invalid scheduled transition. At most, make the scheduling of an invalid transition impossible.
