I attached a PR that accomplishes this. It seems that we're just constantly adding and removing the same properties release to release:

• -webkit-min-device-pixel-ratio
• -o-tab-size
• -webkit-clip-path.

This seems to have been happening since 6.2 in [55139], [55150], [56279], [56948] and [56956]. I don't love that we're just churning code back and forth even in built files.

Looking at -webkit-min-device-pixel-ratio, I'm not sure why this is being added/removed. It looks like this is a ​currently supported property in Safari.

-webkit-clip-path also appears to not be required in versions with enough usage to be added back.

For -o-tab-size, this looks to be happening because Opera Mini (unreleased since 2015) is hovering at 1.029% usage. It's likely fluctuating above and below the currently defined 1% threshold from month to month. It's also required in Opera 11.5-12.1, but all of these are at 0% usage.

I think that we could probably consider dropping Opera from our explicitly defined browserslist in the near future. The entire Opera user base consistently sits at ~2%, and there's always the > 1% rule in the browserslist. More research will need to be done, though, to determine how that ~2% translates to WordPress users.

@desrosj Do we need package-lock.json changes?

@mukeshpanchal27 In this case, yes. The package that needs to be updated is not a direct dependency, so it's only defined within the lock file.

Yes, we hit problems and cherry-picked the package-lock changes here to unblock this work: ​https://github.com/WordPress/wordpress-develop/pull/5922#issuecomment-1910673494

When this PR lands that removes a blocker 👍

I'm going to commit this since this blocks other work and is a reasonable change to make. But I do have some concerns around the frequent churn related to these updates has caused recently. I documented these changes on the Trac ticket.

In 57363:

Build/Test Tools: Update the caniuse data.

This updates the caniuse-lite database and includes all resulting CSS and built file changes, which are all minor changes due to fluctuations in browser usage.

Props gziolo, jonsurrell.

Going to close this out. If another update is needed before final release, this ticket can be reopened.
