Problem: On phone-width viewports (~375-430px), the floating
FormattingToolbar in EditableCell rendered as a single row with
17+ controls (B/I/U + 7 color swatches + 3 align buttons + font +
size + Save/Cancel). The row was wider than the screen, so users
only saw the edges (X, ✓, two "default" dropdowns) and could not
reach Bold/Italic/Underline, color swatches, alignment, or font
controls. The horizontal clamp also relied on the table's
scroll-container bounds, which on mobile extend beyond the viewport
because the table is wider than the screen — so the clamp could
park the toolbar partially off-screen.
Fix in artifacts/tx-os/src/components/editable-cell.tsx:
- Toolbar container: `flex` → `flex flex-wrap` with `gap-x-1 gap-y-1`
and `max-w-[calc(100vw-16px)]` so it wraps onto multiple rows
whenever a single row would exceed the viewport. Bumped `py` to
`py-1` for breathing room between wrapped rows.
- Horizontal clamp: in addition to the scroll-container bounds,
also clamp against the viewport (`[8, window.innerWidth - tbWidth
- 8]`) so the toolbar always lands fully on-screen even when the
scroll container is wider than the screen.
Scope: visual / positioning only. No changes to TipTap config,
toolbar buttons, or save/cancel logic. Above-vs-below placement
(#581 iOS keyboard handling) is preserved.
