1659649 - Compatibility panel warns about CSS cursor property, which is fairly harmless and not actionable

Status: RESOLVED WONTFIX

(DevTools :: Inspector: Compatibility, defect)

Description

[Philip Jägenstedt [:foolip]]

Thank you for helping make Firefox better. If you are reporting a defect, please complete the following:

What were you doing?

Please tell us what site you were on, and what steps led to the error you are reporting

1. Visit https://dom.spec.whatwg.org/ in Firefox Developer Edition
2. Look at the compatibility panel in DevTools.

What happened?

Many instances of the cursor property are flagged. These come from the .dfn-paneled { cursor: pointer; } CSS inline in the file itself.

What should have happened?

Flagging this because it's not supported on Android WebView or Firefox for Android is not useful, as mobile browsers don't have cursors at all by default. When connecting a bluetooth mouse to an Android tablet this might be an issue, however.

Even if one supports these browsers, accepting that the cursor won't be shown is the only course of action, so the warning isn't actionable.

Anything else we should know?

https://github.com/mdn/browser-compat-data/pull/4111 is the BCD update which marked cursor as not supported in Firefox for Android.

Thanks for the suggestion, Philip!

To filter these issues, we'd have to build and maintain a map of actionable properties per device type. As you mention, in some circumstances that mapping may be blurry. With our limited resources, it's unlikely we can handle this in the near future.

Right now, the Compatibility panel uses data as is from the MDN Compatibility repository. Perhaps it's more actionable to open this issue on that project. Its results feed into the Compatibility panel in Firefox DevTools.
