I think someone just broke the new Style Panel (beta).
If you try to apply transform move to an element using percentage, it’ll just turn back to px, even if you select it from the dropdown menu. Turning off beta panel solves the issue tho, but its a bit of a hassle.
Tested it with other computers too using 2 other different accounts, apparently its server-side not just on my browser.
Please check devs. Thanks!
