Currently, there are 8 pairs of properties that share a computed style:
* background-clip, -webkit-background-clip
* background-origin, -webkit-background-origin
* background-size, -webkit-background-size
* box-shadow, -webkit-box-shadow
* mask-clip, -webkit-mask-clip
* mask-composite, -webkit-mask-composite
* mask-mode, -webkit-mask-source-type
* text-combine-upright, -webkit-text-combine
This is a non-standard hack. CSS Cascade defines 2 standard ways: https://www.w3.org/TR/css-cascade-5/#aliasing
* legacy name aliases, for properties with the same exact syntax
* legacy shorthands, for properties with different syntax
So the -webkit- properties above should be turned into aliases or shorthands.
The current hack is more likely to break things, e.g. revert-layer was broken before bug 238125, and CSSOM is still broken (bug 238874).

Bug 104805 is an example of legacy shorthand.
