When I type: I see documentation for another addListener

[vitaly-zdanevich]

I have
https://developer.mozilla.org/en-US/docs/Mozilla/Add-ons/WebExtensions/API/runtime/onMessage#addlistener_syntax

but it shows
https://developer.mozilla.org/en-US/docs/Web/API/MediaQueryList/addListener

Is it CoC itself or some plugin?

The content is from language server, check the language server you use.

I do not know what language server, looks like the default for JS.

Can such popups show the language server name, at the bottom?

Check :CocList services
