When a page-level information banner is visible on a record table (e.g.
the mailbox **"Sync lost with mailbox … Please reconnect"** banner), the
table footer / bottom edge was hidden behind the card boundary. As a
side effect, drag-select **auto-scroll never triggered** near the
bottom, because the cursor could not reach the scroll wrapper's real
bottom edge.
## Root cause
In `PageCardLayout`, the `InformationBannerWrapper` and the page
children are siblings in a flex column. The record index child
(`StyledIndexContainer`) used `height: 100%`, so it demanded the
**full** body height regardless of the banner. With a banner present,
banner height + 100% exceeded the card, and since the container's
content (the table) has a large min-content height it would not shrink —
so the bottom (the footer) was pushed past `StyledCard`'s `overflow:
hidden` and clipped.
`useDragSelectWithAutoScroll` only scrolls when the cursor is within
`AUTO_SCROLL_EDGE_THRESHOLD_PX` (20px) of `containerRect.bottom`. With
the bottom edge clipped off-screen, that zone was unreachable, so
auto-scroll appeared broken.
## Fix
Replace `height: 100%` with `flex: 1; min-height: 0;` so the container
takes the space **remaining** after the banner — the same flex idiom its
parent `StyledBodyContent` already uses. When no banner is shown, the
banner wrapper collapses to `height: 0`, so the table fills the full
height exactly as before (no behaviour change in the common case).
## Testing
- Verified locally: with the mailbox reconnect banner forced visible on
the Companies table, the footer (aggregate row) stays visible and
drag-select auto-scroll reaches the bottom.
- No change when no banner is present.
This is a layout fix, not a drag-select threshold change — as suggested
in the issue, raising the threshold would only mask the layout problem.
