LGTM, assuming it doesn't break IE9. We could probably add a style fixture that just sets every style value and verifies its set on the node.
Looks like you need to remove the |
Does anybody want to test if it breaks IE9? If this is a one-off for IE8 I don't think it deserves a fixture. |
@gaearon it may have been included for IE8, but there's no guarantee that a fix isn't directly or indirectly preventing a break in other browsers as well, which is why I recommended a broad fixture for style properties. I say that because I thought that it had happened to me before, and it turns out it was when I tried to do this exact same thing in #9294 😄 This was breaking iOS 4 and Android 4.1 for me, so I dropped it since I wasn't sure what our browser support guidelines were (#9301) |
Based on @aweary's experience, it sounds like we need to determine if are dropping support for iOS4 Safari and Android 4.1 Browser. caniuse indicates 0% usage of iOS 4 Safari and 0.11% usage of Android 4.1 Browser globally. still, I do not know how representative this is of Facebook's audience. So do we drop these browsers? |
IIRC our guideline is > 1% of our audience. But @sophiebits can confirm whether I remember it right. |
Did some quick visual QA in IE8-11 and Android 4.2. Some of my best design work, of course: This also looked great on the Galaxy S3's native browser which makes me wonderif I'm missing a key step in QA based on @aweary's experience. But this looks good to me otherwise, 👍. |
@nhunzaker I believe I had issues with Android 4.1, not 4.2. it's also totally possible I messed up the QA last time somehow 😉 |
@aweary sorry, I missed a key detail: The Galaxy S3 I tested on was Android 4.1. I just did another check to very that styles can be toggled on or off, which, I think, covers the shorthand bug style clearing case. I've published that here: http://react-shorthand-style.surge.sh/ For whatever it's worth, this does work on Android 4.1. I think we should move forward with this change. |
We’ll wait for after 16 before landing. Since we’ll probably land a few PRs that increase the bundle size (e.g. new unstable APIs) and I want to have something to balance that. |
I verified the @nhunzaker's fixture works as expected in Android 4.1, so this LGTM whenever we want to merge 👍 |
We don’t support it anymore.
Just need to verify IE9 is not affected.
