Walkthrough

A single CSS property, max-height: inherit;, was added to the .sticky-wrapper class in two LESS files related to table grid styling. No other logic, control flow, or exported/public entity changes were made.

Changes

Files	Change Summary
packages/theme-saas/src/grid/table.less, packages/theme/src/grid/table.less	Added max-height: inherit; to .sticky-wrapper class

Poem

In the land of sticky tables,
Where wrappers cling and climb,
A max-height now inherited,
Keeps grids neat and in line.
With a hop and a CSS tweak,
Our tables look sublime!

1255-1262: Avoid style divergence – extract the shared rule

The same max-height: inherit; patch now exists in both theme files.
To reduce maintenance cost and avoid future divergence, consider extracting this rule into a shared mixin (or reuse an existing one) and include it from the two theme bundles instead of duplicating raw lines.

1436-1443: Ensure the new max-height actually propagates

max-height: inherit; only has an effect when a finite max-height is defined on an ancestor.
Please confirm that the parent of .sticky-wrapper (typically the body wrapper) sets an explicit max-height, otherwise this rule will be a no-op and the original scroll issue may remain unaddressed.
If the parent is expected to rely on inline styles calculated at runtime, consider adding a fallback (e.g., via a CSS variable) to guarantee determinism across themes/frame integrations.
