Scriptables' context is missing elements and options

I’m using a scriptable display property to control when annotations can be shown, based on their options. (This is the same use case I’d originally asked about in #244.) This was working in an earlier copy of chartjs-plugin-annotation (circa December 2020), but in the current 1.0.0-rc, it’s giving problems:

• The first time display is called, the context parameter’s element member is completely missing.
• The second time it’s called, element is present, but it has no options member.

If display is called again (for example, because the chart updates from showing or hiding a dataset), then element.options is correctly populated.

See https://codesandbox.io/s/chartjs-annotation-context-c95k6 for a demo. The console will show error messages when the page is first loaded. Clicking a dataset’s legend item to show or hide the dataset will cause the annotations to be correctly shown or hidden.

I created #388 to track the options.type discrepancy. I apologize for the delay in getting back to this. Thanks for your help!

I can open a separate issue for this or try and open a PR for this as well if you like.

Separate issue would be good. This can be closed after that?
