1457297 - Enable shape-outside for all channels

Status: RESOLVED FIXED

(Core :: Layout: Floats, enhancement, P2)

Description

[Maire Reavy [:mreavy]]

Shape-outside is pref'd on in Nightly, but not Beta and Release for Fx 61.  This bug tracks enabling Shapes-outside for all revisions.  We should land this early in Fx 62.

Hi Brad -- Since Nightly is now Firefox 62, we need to enable for all revisions.  Do you agree the feature is ready to ride the trains?  If so, can you land the patch to enable it this week?

This is a new feature, so the priority is officially a P2, but we *definitely* want this in 62.  (Thanks, Brad!)

Are there shared tests of shape-outside in web-platform-tests?  If so, are there any that we fail, and what bugs correspond to those failures?

Is the entire feature implemented, or are there missing pieces?  If so, what bugs correspond to those pieces?

Did you send an intent-to-ship to dev-platform?  See https://wiki.mozilla.org/ExposureGuidelines .

We do still fail some tests, but they don't have associated bugs:

/css/css-shapes/shape-outside/shape-image/shape-image-024.html - our PNG upscaling doesn't create a clean edge pixel, and it introduces a sub-pixel shift in the final placement.
css/css-shapes/shape-outside/shape-image/gradients/shape-outside-radial-gradient-004.html.ini - our radial gradient generation doesn't exactly match expectations and introduces sub-pixel placement defects.
css/css-shapes/spec-examples/shape-outside-008.html - our detection against a polygon is off by sub-pixel amounts.

All of the above are cases where we've got minor fuzziness in the final placement. WPT don't allow for fuzzy matches. If they did, we'd likely pass.

css/css-shapes/spec-examples/shape-outside-004.html - we've intentionally deviated from spec here in anticipation of the spec changing, see Bug 1461046.

There are two pending bugs, and they both are blocking the main meta-bug Bug 1098939:
Bug 1466231 - Inline frames without enough inline space should clear floats, regardless of shape-outside. This has knock-on effects in non shape-outside tests that are still being worked through.
Bug 1463745 - The Text around shape-outside does not fill the empty space [shape-outside]. This is a simpler case that has tests that depend on the previous bug, but is otherwise ready to land.

I have just done so. I set a target for landing this bug on Monday June 11th.

I've updated the compat data for shape-outside, shape-margin, and shape-image-threshold:

https://developer.mozilla.org/en-US/docs/Web/CSS/shape-outside
https://developer.mozilla.org/en-US/docs/Web/CSS/shape-margin
https://developer.mozilla.org/en-US/docs/Web/CSS/shape-image-threshold

I think that's all we need here, so I'm marking this dev-doc-complete, but please let me know if we need anything else.
