Stash actions not working correctly when multiple apps use Stash in a Layout

[yurytaranau]

Description

When a Layout includes Stash Left (or other Stash directions) as an action for multiple applications alongside sizing actions (e.g., First Third), the Stash does not apply correctly. The sizing action works as expected, but Stash either partially applies or silently fails.

Steps to Reproduce

1. Create a new Layout.
2. Add multiple applications to the Layout.
3. For each application, assign two actions:
   • A sizing action (e.g., First Third)
   • Stash Left
4. Trigger the Layout.

Expected Behavior

All configured applications should be stashed to the left edge of the screen. Each stashed app should appear as a colored tab on the left edge, and all stashed apps should be listed under Unstash in the menu bar dropdown.

Actual Behavior

• Only one colored tab appears on the screen edge instead of multiple tabs (one per stashed app).
• The Unstash submenu in the menu bar shows no stashed applications — it is empty.
• The sizing action (e.g., First Third) is applied successfully to all apps.
• Stash appears to be silently ignored or overridden for all but one app (and even that one is not properly registered as stashed).

Additional Context

• The issue reproduces even when Stash Left is the only action assigned to each app in the Layout (no sizing actions at all). The result is the same: one colored tab may appear, but no apps are listed in the Unstash menu.
• If Stash Left is triggered manually via hotkey for a single app outside of a Layout, it works correctly.
• The issue seems specific to Stash being triggered through Layout automation, regardless of whether other actions are present.

Environment

• Rectangle Pro v3.68
• macOS Tahoe 26.2

Thanks for reporting. I think I see what's going on here and will push out a fix soon.
