@Simon - I am only able to find four references to "alphaComponent" in Webkit GitHub, while noticed that these clean-up patches landed in Webkit in 2020: https://github.com/WebKit/WebKit/commit/1a972b5062db8b61e5217bd35986f8dbdd36b75e https://github.com/WebKit/WebKit/commit/65cd1e76a0bd628e1cd2109a0dd8bb7d9000b86c https://github.com/WebKit/WebKit/commit/76dea7243010f7a3aada8d7f42ad336d6ca153ba https://github.com/WebKit/WebKit/commit/1cf4a24fb0220174c7db4d6e5e3b245cc86e8f07 Do we need to do something more here? If it has been resolved, can we mark this and "See Also" related bug as "RESOLVED CONFIGURATION CHANGED"? Thanks!
