Text overlaps when renaming a printer

[FelipeFMA]

When renaming a printer the new text overlaps with the old name, making it hard to read or edit. The expected behavior is for the text field to completely replace the old name or clear it upon entering edit mode.

Steps to Reproduce:

1. Open system-config-printer.
2. Right-click on a configured printer.
3. Select the "Rename" option.
4. Start typing a new name.

Expected Result:
The input field should:

• Display only the new text being typed.
• Clear the old name automatically when renaming starts.

Additional Information:

• Operating System: Arch Linux with Sway (Wayland).
• system-config-printer version: 1.5.18-5 (official Arch Linux extra repository).

When opening the application, the following warnings are displayed in the terminal:
