scaleX "only “0” can be a “unit”. You must put a unit after your number" error

[ashleyryan]

We regularly validate our CSS against the service and within the last 12 hours so we started getting an error that a transform: scaleX(1) value isn't valid and needs a unit. My understanding is that that's not true, and scale uses a multiple. MDN doesn't show a unit. Is this a bug?

I suspect it may be related to this PR? #438

Thanks for the report, it was indeed a side effect of #438
