…[patch] BorderElement measured its child without the width its parent passed in, and a horizontal StackPanel measured children width-independently, so word-wrapped text in either reported one unwrapped row and only its first line was drawn. BorderElement now forwards the width inside the border, and a horizontal StackPanel measures each child against the width its earlier siblings and the spacing leave, in both arrange and measure. Replaces the test that locked in the border's width-blind measure.

Fixes #161
What changed
BorderElementoverrides the width-awareOnCalculateRequiredDimensionsForChildren(int)and forwards the width inside the border to its child. The title-width rule from BorderElement title is truncated or not drawn at all because the border's measured width ignores the title #157 is shared between both overloads.StackPanelmeasures each child against the width still free:contentArea.Width - currentOffsetwhen arranging, and the available width minus earlier siblings and spacing when measuring. Width-independent measures (no width given) are unchanged.Tests
ContainerWithoutAWidthAwareLayoutMeasuresTheSameWithAWidth, which locked in the old behaviour, with five tests:TUI.Testsuite passes (260/260).🤖 Generated with Claude Code
