New Chrome ignores CSS vars with no name

[at-nathan]

Describe the bug Current Chrome as of posting (105.0.5195.102) will ignore CSS var defined with no name (i.e. --)

/* Will be stripped by chrome */
--: black;
/* Will be ignored by chrome */
--named-var: var(--);

Compiled currently uses this var name for empty var values. This is preventing the upgrade of loki as VR tests are failing due to it using affected newer version of Chromium.
