I'm not seeing any issue when I enable `layout.css.webkit-fill-available.enabled` (it's on by default in nightly builds). Raul, is that maybe why you're seeing an issue here? I suppose we can ship an intervention for builds where that flag is disabled...

I'm not seeing any issue when I enable `layout.css.webkit-fill-available.enabled` (it's on by default in nightly builds). Raul, is that maybe why you're seeing an issue here? I suppose we can ship an intervention for builds where that flag is disabled, but they seem to be using webkit-fill-available all over the place in their CSS, including on widths, so it might not be easy to figure out work-arounds for all of the potential breakage.
