Firefox displays "Attempting to connect..." in the API Status box

Description

With a new install of Prefect server (0.12.5), Firefox (78.0.2, Linux) displays "Attempting to connect..." in the API Status box. Chrome (84.0.4147.89, Linux), however, displays "Connected".

Expected Behavior

Both Firefox and Chrome to connect to the API.

Reproduction

I've attached a screenshot of Firefox, with the network tab open: this shows that the response from the API is 200 even though the API Status box displays "Attempting to connect...".

Environment

Here's the output of prefect diagnostics.

}
