WalkthroughDataGridView now virtualizes rows only when the row count exceeds a configurable threshold. Smaller grids render all rows in normal document flow with static positioning, while larger grids retain virtualized measurement and positioning. ChangesData grid rendering

The tests validate only a two-row default grid and a 150-row grid. They do not validate that exactly 100 rows use static flow or that

the mutated request. Keep the existing forbidden response and membership-only

Render cost tracks total cells (rows * cols), not row count alone, so a flat row threshold under-virtualises wide grids. Scale the default threshold by visible column count instead, clamped to [25, 400]. Formula and bounds adapted from VIBVEL47's independent fix for the same issue in pgadmin-org#10146.

What this is
SchemaView dialogs keep inactive tabs mounted with
display: none. EveryDataGridViewcollection grid is always virtualised via@tanstack/react-virtual, withmeasureElementdoing a synchronousgetBoundingClientRect()on every row through a fresh ref callback. Whilst a tab is hidden its scroll viewport measures 0, so the virtualizer'sResizeObserversees a 0-to-real-height jump when the tab is shown again and treats it as a resize, re-measuring every row from scratch — slow for large grids, and pure overhead for small ones that had no offscreen window to skip in the first place.Fixes #10143.
Fix
Added a
virtualiseThreshold(overridable viaviewHelperProps.virtualiseThreshold, matching the existingvirtualiseOverscan). Grids at or under the threshold skip virtualisation entirely: nomeasureElementref, rows render via a plain.map()in normal document flow, and a newpgrt-row--staticclass overrides the row's usualposition: absolute. Hide/show for these grids is now a pure CSS toggle with nothing for the virtualizer to remeasure. Grids above the threshold are unchanged.The default threshold scales with visible column count (
min(400, max(25, round(700 / cols)))) rather than being a flat row count, since render cost tracks total cells (rows × cols), not rows alone. That formula and its bounds are adapted from @VIBVEL47's independent fix for the same issue in #10146 — credit there, folded in here to keep one PR moving rather than two duplicates. Thank you for the fix, @VIBVEL47.Test plan
