Webflow will now show globals in the auto-complete list as you type new classes, however these suggestions will be paired with a warning that makes it more clear that styles will be inherited.

More details about the new class selector UI posted here: Details about recent class/selector user interface changes - Webflow announcements - Forum | Webflow
I’m really sorry for the flubbed rollout of these changes without a proper announcement before hand. We’re working on modifying our development schedule and beta process to get feedback earlier in the process so there are no surprises.
As always, we’re thankful for the entire community for challenging us and helping us build the world’s best web design software. Keep the feedback coming - we’re listening!
