[Overlay Plot] Should not accept Imagery on Drop

[jvigliotta]

Currently you can drag and drop example imagery in to an overlay plot.

Steps to Reproduce

• create overlay plot
• create example imagery
• drag example imagery into overlay plot
• observe nothing shows up, but the example imagery is in the composition and inspector view
• errors for 'unit' are also being thrown

This seems to be a regression, maybe with the type def of imagery

@michaelrogers I would first check that this is reproducible and then let's talk about next steps.

Might need a tweak to the plot's "composition policy".

@akhenry - I am not able to immediately reproduce this issue. I'm double checking my overlay plot configuration and attempting a few edge cases but I did not see evidence of the image being added to the composition when I inspected the exported JSON of the plot.

@akhenry - What is the correct process for closing an issue that seems to have been resolved previously. Should I close and mark with the Unverified tag?

[akhenry]

@michaelrogers Ah! yes, close it and add an unverified label. That way it will get picked up in the next round of testing. Once it's confirmed fixed by testing, we will remove the unverified label.
