- fall back to plain UIVisualEffectView when glass APIs are unavailable - guard glass effect runtime access behind capability checks - request layout for iOS 18+ label text changes even for fixed-size labels - add automated regression coverage for liquid glass effect updates

Update the iOS LiquidGlass FlexboxLayout test to compare the fixed 300 DIP container height using device pixels. The layout helper reports pixel sizes, so 300 DIP correctly renders as 900 px on a 3x simulator; this fixes an outdated test expectation rather than a flexbox regression.

Remove the unrelated Label layout invalidation change and simplify glass support back to the SDK gate requested in PR review. Also drop runtime glass style global lookups and restore temporary measure-state overrides in finally blocks so the flexbox fix remains scoped and safe.

Thank you for the adjustments @VeinDevTtv - one last small thing; is it possible to add a quick FlexboxLayout example in https://github.com/NativeScript/NativeScript/blob/main/apps/toolbox/src/pages/glass-effects.xml so it's easily seen in toolbox for this case now and in future? |

What is the current behavior?
Currently on iOS, placing a
LiquidGlassorLiquidGlassContainercomponent inside aFlexboxLayoutcompletely breaks the layout (children are measured incorrectly and positioned at the wrong coordinates). This is because LiquidGlass overrides_addViewToNativeVisualTreeto use a nested_contentHostview, which mismatches FlexboxLayout's standard measurement and layout paradigms.What is the new behavior?
Measurement fix: Overrode
onMeasurein bothLiquidGlassandLiquidGlassContainerto temporarily zero out padding/border properties before delegating tosuper.onMeasure(). This preventsGridLayout/AbsoluteLayoutfrom double-subtracting padding thatFlexboxLayoutalready removed from the child measure spec.Layout fix: Overrode
onLayoutin both classes to callsuper.onLayout(0, 0, right - left, bottom - top). SinceFlexboxLayoutpositions the rootUIVisualEffectViewusing absolute coordinates, the internal NativeScript layout engine needs normalized(0, 0, width, height)bounds to correctly position children within the local_contentHostcoordinate space.Fixes #11099.
