Error with displaying the API operation details on APIDetails page in private Firefox mode

[ZarTrox]

Bug description

Currently when opening the APIDetails page of a DevPortal environment in the private Firefox browsing mode the operation details of some APIs are loading infinitely.

APIDetails page with an loading API operation details widget:

Loading API operation details widget:

When checking the console for errors the following message is displayed: Uncaught (in promise) DOMException: A mutation operation was attempted on a database that did not allow mutations.

The bug does not occur in all APIs but multiple are affected. The issue is only visible in Firefox. Edge and Chrome are working as expected.

Reproduction steps

1. Open private mode in Firefox
2. Sign in to a DevPortal environment
3. Select an API until the API contains the error
4. Check console

Is your portal managed or self-hosted?

I can confirm the issue is still there. It's specifically in firefox Private mode. Regular mode works fine, even with ublock, strict security enabled and various other privacy stuff.

At first I thought it was firefox itself, didn't check non-private mode. My workflow for this is managing the dev portal as usual, then opening private mode as a "new session" window, to see the "regular user" flow.

Let me know what additional details you might need for this. But the initial post has the same information that I see myself.

Update: Right now, at least with the newest firefox (121.0.1, haven't checked versions before this) everything seems to work for me. No idea if it's the updated firefox, or maybe something updated in the developer portal that fixed it.
