• Component: Layout and Rendering
• Status: NEW

[Marta Darbinyan]

The following tests are failing on iOS26. They might be the candidates for rebaseline. The regression occurs between iOS16->iOS26 update.

These should be rebaselined:
fast/viewport/ios/responsive-viewport-with-minimum-width-after-changing-view-scale.html
fast/viewport/ios/shrink-to-fit-for-page-without-viewport-meta.html
fast/viewport/ios/viewport-fit-auto.html
fast/viewport/ios/viewport-fit-contain.html
fast/viewport/ios/viewport-fit-cover.html
fast/viewport/ios/width-is-device-width-overflowing-body-overflow-hidden-tall.html
fast/viewport/ios/width-is-device-width-overflowing-body-overflow-hidden.html
fast/viewport/ios/width-is-device-width-overflowing-no-shrink-to-fit.html
fast/viewport/ios/width-is-device-width-overflowing.html
fast/viewport/ios/width-is-device-width.html

These ones should not be:
fast/viewport/ios/shrink-to-fit-content-large-width-breakpoint.html
fast/viewport/ios/use-minimum-device-width-for-page-without-viewport-meta.html
