## Summary
Fix right-side sidebar panels and left-side panels sharing the same
PrimeVue Splitter state key, causing them to incorrectly apply each
other's saved widths.
## Changes
- **What**: Make `sidebarStateKey` position-aware by including
`sidebarLocation` and offside panel visibility in the localStorage key
## Problem
When sidebar location is set to **right**, all panels (both the
right-side sidebar like Job History and left-side panels like Workflow
overview) share a single PrimeVue Splitter `state-key`
(`unified-sidebar`). PrimeVue persists panel widths to localStorage
using this key, so any resize on one side gets applied to the other.
### AS-IS (before fix)
The `sidebarStateKey` is computed without any awareness of panel
position:
```typescript
// Always returns 'unified-sidebar' (when unified width enabled)
// or the active tab id — regardless of sidebar location or offside panel state
const sidebarStateKey = computed(() => {
return unifiedWidth.value
? 'unified-sidebar'
: (activeSidebarTabId.value ?? 'default-sidebar')
})
```
This produces a **single localStorage key** for all layout
configurations. The result:
1. Set sidebar to **right**, open **Job History** → resize it smaller →
saved to `unified-sidebar`
2. Open **Workflow overview** (appears on the left as an offside panel)
→ loads the same `unified-sidebar` key → gets the Job History width
applied to a completely different panel position
3. Both panels open simultaneously share the same persisted width, even
though they are on opposite sides of the screen
This is exactly the behavior shown in the [issue
screenshots](https://github.com/Comfy-Org/ComfyUI_frontend/issues/9440):
pulling the Workflow overview smaller also changes Job History to that
same size, and vice versa.
### TO-BE (after fix)
The `sidebarStateKey` now includes `sidebarLocation` (`left`/`right`)
and whether the offside panel is visible:
```typescript
const sidebarTabKey = computed(() => {
return unifiedWidth.value
? 'unified-sidebar'
: (activeSidebarTabId.value ?? 'default-sidebar')
})
const sidebarStateKey = computed(() => {
const base = sidebarTabKey.value
const suffix = showOffsideSplitter.value ? '-with-offside' : ''
return `${base}-${sidebarLocation.value}${suffix}`
})
```
This produces **distinct localStorage keys** per layout configuration:
| Layout | Key |
|--------|-----|
| Sidebar left, no offside | `unified-sidebar-left` |
| Sidebar left, right panel open | `unified-sidebar-left-with-offside` |
| Sidebar right, no offside | `unified-sidebar-right` |
| Sidebar right, left panel open | `unified-sidebar-right-with-offside`
|
Each configuration now persists and restores its own panel sizes
independently, so resizing Job History on the right no longer affects
Workflow overview on the left.
## Review Focus
- The offside suffix (`-with-offside`) is necessary because the Splitter
transitions from a 2-panel layout (sidebar + center) to a 3-panel layout
(sidebar + center + offside) — these are fundamentally different panel
configurations and should not share persisted sizes.
