Less.js: Variable @supports is undefined on v3.10.x

Created on 18 Jan 2020 · 4Comments · Source: less/less.js

Looks like support for CSS's "@support" is broken after v3.0.4, any ideas? change-log doesn't seem to have anything about it

I'm surprised there's not a specific test for this. Looks like it was missed. Will investigate.

@awebdev I'm not sure what's going on for you, but there are lots of tests for @supports, and using your example on the latest version of Less (3.12.2), it compiled fine. 🤷‍♂️

Still, I'm getting the same error on v3.12.2 with less-loader v7.1.0
