On Android, giving a checkbox or radio width:auto seems to collapse them, as though they have no intrinsic width anymore. A simple test-case show this:

<!DOCTYPE html>
<html>
<body>
With width:auto
<input type="checkbox" style="width:auto">
<input type="radio" style="width:auto">
Without width:auto
<input type="checkbox">
<input type="radio">
</body>
</html>


Based on a regression range found on webcompat.com (in the see-also link), I suspect this is related to bug 605985, so I've tentatively set that as a dependency.

Summary: Checkboxes and radios on Android no seem to have a zero width when width:auto is used → Checkboxes and radios on Android don't seem to have a zero width when width:auto is used
Not yet try on a local build without mats patches, but from nightly builds[1,2], it looks it's the case. 

OK: https://ftp.mozilla.org/pub/mobile/nightly/2017/02/2017-02-09-11-01-55-mozilla-central-android-x86/
NG: https://ftp.mozilla.org/pub/mobile/nightly/2017/02/2017-02-13-00-46-19-mozilla-central-android-x86/

Note that, in OK build, the checkbox is not checkable and its width is narrower that intrinsic size.
Blocks: 605985
No longer depends on: 605985
Right, I should have #ifdef'ed out those changes more thoroughly for Android/Gonk.

Thanks, dholbert! I just verified that this patch makes my testcase in comment 0 work as it does in 51.0.3 on my phone.

However, the results do confuse me. In my testcase in comment 0, the box/radio that have a width specified end up being narrower than the ones with no width specified (as in, the radio is an oval). But this is what the code has always been done, and I'm not sure whether this is something that should be fixed:

>  static nscoord DefaultSize()
>  {
>    // XXXmats We have traditionally always returned 9px for GetMin/PrefISize
>    // but we might want to factor in what the theme says, something like:
>    // GetMinimumWidgetSize - GetWidgetPadding - GetWidgetBorder.
>    return nsPresContext::CSSPixelsToAppUnits(9);
>  }
Yeah, I think that's always been a bug on Android.
We need to re-implement checkbox/radio on Android anyway to be web-compatible
so I don't think it's worth tweaking this patch further.

Make checkbox/radio controls have a default (non-zero) size also when -moz-appearance:none on Android/Gonk (since that's the default on these platforms).  r=dholbert

Mats, do we already have a bug for it ?

We're discussing it in bug 1340661, I'm hoping Mike could pick it up
and fix it there.  If not, I'll make sure to file a new bug.
