[Bug]: Stuck custom blur region after removing widget

[luisbocanegra]

I have:

• Searched if this issue hasn't been reported yet.
• Verified that I am using the latest version (see Widget settings > About page or top right corner for version 1.1.0 and later), should be the same as https://github.com/luisbocanegra/plasma-panel-colorizer/releases/latest

Install method used:

• Using Plasma's "Add new widget" (KDE Store)
• AUR
• Nix package
• Manually from the latest source code

Describe the bug

Removing a widget from the panel when custom blur per widget is enabled leaves a stuck blur area

Steps to reproduce

1. Enable 'Blur Widgets' preset
2. Enter edit mode and remove any widget that is not 'Panel Colorizer' from the panel

Observed Result

A blur will appear to the right side of the panel and doesn't go away until restarting plasmashell

Expected Result

Blur region should be properly removed
