Unprefix (behind a setting?) properties tested in WPT

Summary Unprefix (behind a setting?) properties tested in WPT
Sam Sneddon [:gsnedders]
Reported 2020-10-09 11:00:48 PDT
Currently, the WPT test importer rewrites tests during import in various ways. As part of the work to improve syncing between WebKit and WPT, it would be desirable to get rid of this rewriting. Part of this involves adding the -webkit- prefix to certain properties, so that we can test our prefixed implementation of various features. The properties effected for which tests exist are: appearance aspect-ratio backdrop-filter backface-visibility box-decoration-break mask mask-box-image mask-clip mask-composite mask-image mask-origin mask-position mask-repeat mask-size ruby-position text-align-last text-justify text-size-adjust user-select Additionally, there are tests for the following in WPT which we fail to rewrite: initial-letter line-clamp mask-position-x mask-position-y It would be nice to unprefix these, either unconditionally or behind a setting we can enable for tests, so that we can run the WPT tests for them unmodified.

Okay, so https://github.com/web-platform-tests/wpt/pull/26070 gets rid of the one instance of mask-box-image in WPT, and the references to mask-position-x/mask-position-y don't actually do anything, which leaves us only with properties where the unprefixed versions have current specs.

So, 2023 update: Properties we don't support unprefixed which appear in WPT: 1 mask-position-x 1 mask-position-y 3 text-size-adjust 36 user-select 37 box-decoration-break 47 initial-letter 63 ruby-position 81 backdrop-filter I can't find any usage of any CSS value we only support prefixed.
