Make Breadcrumb work on Post methods

[johnstaveley]

I have the following method:

        [Breadcrumb("Usage", FromAction = "Index", FromController = typeof(ReportsController))]
        [HttpPost] // TODO: Breadcrumb does not work on any method decorated with Post
        [HttpGet]
        public async Task<IActionResult> Usage(StudentUsageDataModel usageModel)

If I remove [HttpPost] the breadcrumb appears, if present, it does not. Is this a bug or intentional? Can it be fixed?

As an input. Breadcrumbs by attribute do not to work on HttpPost for me as well. But they work when defined manual. I would be happy as well if they would work as attribute. My use case is when i want to post a form, but the modelstate is not valid, then i return the page from the post controller action. If save is successfull the action is redirected to the corresponding get of the object created, where breadcrumbs work as attribute.
