Error if no previous rule or declaration exists #220

Open jednano opened 4 years ago

jednano commented 4 years ago

Error is thrown here when the rule is undefined:

https://github.com/postcss/postcss-custom-properties/blob/a250907b9ca0b336d6c0ca948a1db2fe2d145309/src/lib/is-ignored.js#L5

Fix should probably be implemented here to check if the rule exists before sending it to isBlockIgnored.

Unfortunately, I don’t remember the scenario. Can’t believe I didn’t include that here. Sorry.
