My tasks page shows tasks the user can view but not edit causing an error when checking the task

Assign a user a task on a page to which they only have view permission for.

That user will see the task assigned to them in the my tasks page. That is good. However, they should not be able to check the task - or they should at least get an appropriate error message about not being able to edit the page (hence not being able to check the task). Currently it just shows an ugly misleading error message when checked.

Ideally you would have a disabled checkbox instead and a tooltip explaining that you don't have edit permission but do have view permission. But then this bug occurs for the actual view page too.
