Device labels hidden when images are enabled in Rack view

[lschweiss]

Environment

• Nautobot version (Docker tag too if applicable): 1.5.4
• Python version: 3.9
• Database platform, version: Postgres 14
• Middleware(s): N/A

Steps to Reproduce

1. Add a device to a Rack
2. Add a device name and image for the device

Expected Behavior

Expect the device name to show over the image

Observed Behavior

The device name is seen for a split second as the page loads. Then the image is rendered over the device name.

With images enabled:

With images disabled:

Looking at the code, the primary cause is the order of images being added in nautobot/dcim/elevations.py.

Putting the if self.include_images code before the link.add() statements get the labels on top. However, they also need a shadow rendered, or the text is not always legible.

I think an issue here is the legibility of your example which I believe is why this approach was chosen. However, maybe a text background can be applied to help with that.

I loaded the same data in Netbox. It renders nicely creating shadows:

The code seems to have diverged quite a bit in elevations.py. I'm not more than a python script kiddie, so I don't see an obvious way to duplicate this.
