hsla() with alpha of 0 leads to alpha 1 result

[six7]

From Slack:

The black buttons (screenshot) are supposed to have a transparent background color.

"color": {
      "transparent": {
        "value": "hsla(0, 0%, 0%, 0)",
        "type": "color"
      },

But they are displayed black (Fill #000000 100%).
It seems this issue was introduced with V129 or V130

Is this only us or anyone else using hsla(0, 0%, 0%, 0) and getting instead hsla(0, 0%, 0%, 1) displayed?
