Pull request overview
This pull request updates Ignite UI for Angular’s virtualization measurements to properly account for borders in igxFor item sizing and to use the Excel-style filtering list’s inner (client) height as the virtual viewport size, preventing clipping when borders are present.
Changes:
- Adjusts
IgxForOfDirectivenode size calculation to include border widths in addition to margins. - Updates Excel-style filtering search virtualization to use
clientHeightinstead ofoffsetHeightfor the container size. - Adds regression tests covering bordered sizing for
igxForand the Excel-style filtering viewport sizing.

Closes #17490
Description
Fixes virtualized list sizing when item and container borders are present.
igxFornow includes item borders alongside margins when measuring rendereditems. The Excel-style filtering list uses its inner client height as the
virtual viewport, preventing its own borders from clipping the final item with
the Fluent theme.
Adds regression coverage for vertical and horizontal item sizing and the
Excel-style filtering viewport.
