## Summary
Refactor and cleanup `WorkflowTabs` scroll/overflow handling to improve
stability, ensure proper watcher disposal, and keep the active tab in
view more reliably.
note: honestly a nit, can drop if review is too annoying
## Changes
- **What**:
- Replace `ScrollPanel` ref with `containerRef` and query
`.p-scrollpanel-content` within the container.
- Add computed `scrollContent` to centralize access to the scrollable
element.
- Add `ensureActiveTabVisible({ waitForDom })` option to skip `nextTick`
when not needed.
- Rework watchers with explicit `WatchStopHandle`s and `onCleanup` to
stop previous watchers and dispose `overflowObserver` correctly when
`scrollContent` changes.
- Update arrow enable logic by watching `arrivedState.left/right`
together and setting `leftArrowEnabled`/`rightArrowEnabled` immediately.
- Only measure and re-ensure visibility when overflowing; call
`scrollState.measure()` and `ensureActiveTabVisible({ waitForDom: false
})` after arrows update.
- **Breaking**: None
- **Dependencies**: None
## Review Focus
- Correctness of watcher lifecycle and cleanup when `scrollContent`
changes
- Arrow enablement behavior at scroll boundaries
- Reliability of `ensureActiveTabVisible` across tab selection and
overflow changes
- Regressions in scroll performance and tab visibility
