Subject: [Bug Report]: UI Artifacts and Freezing in v8.0.4 (Regression from v8.0.3)

Dear Zotero Development Team,

I am writing to report a critical UI bug introduced in the latest update that significantly hinders the library management workflow.

Environment:
- Zotero Version: 8.0.4 (Issue not present in v8.0.3)
- OS: Windows 11 25H2
- Note: This issue has been confirmed on Windows; I have not yet tested it on macOS.

Description of the Issue:
1. Initial Freeze: When clicking "Change Parent Item," the selection modal occasionally fails to render. The app enters a "hung" state where only error sounds play upon pressing 'Esc' or 'Enter'. A forced restart via Task Manager is required.

2. UI Artifacts: Upon restarting and retrying, the selection window appears, but a persistent "ghost image" (afterimage) of the right-click context menu remains stuck on the UI. This artifact obscures a significant portion of the library list, making navigation nearly impossible.

3. Behavior: The ghost image only disappears once an item is successfully assigned and the "Change Parent Item" window is closed.

Steps to Reproduce:
1. Right-click an item in the library.
2. Select "Change Parent Item."
3. Observe either the application freeze or the persistent context menu artifact.

This seems to be a regression issue specific to the 8.0.4 update. I have attached a screenshot of the UI artifact for your reference. I would greatly appreciate a fix as this makes heavy library organization very difficult.



Thank you for your assistance.
Best regards.
