==== Reproduction Steps ====
//Note: This can be reproduced without having to change anything with Spaces, as long as the user isn't in the Default View Policy for Maniphest Tasks//
1. Make the Default Space visible to {nav Employees}
2. Create a Space visible to project {nav Contractors}
3. Create a Maniphest Task Form (`/transactions/editengine/maniphest.task/`) that is visible to {nav Contractors}, set as being Edit Form
4. Create a User that is only a member of {nav Contractors} and which does not have access to the default space (not a member of {nav Employees}
5. Change the Default View Policy for Maniphest Tasks to be {nav Employees} (this bug does not seem to be affected by Default Edit Policy)
6. Log in as the new user and attempt to create a new task using that task form. You will be presented with the "Edit Locked Task" form.
====Workaround====
- In the cases I've seen where users are prompted with this, they have the option to "Override Task Lock". Clicking this will allow the user to create a task
