Opacity setting issues when switching to full-screen mode

Hey there!

Thanks for creating SPF! It's tough to come across a good open-source dimming app for macOS.

I've been using SPF for years, and it’s been great! However, I’ve noticed a couple of related issues when switching to full-screen mode while opacity is set (regardless of the value):

Long-standing issue: If you set an opacity value, switch to full-screen mode (e.g., for a video), and then exit full screen, the opacity resets to 0. New issue since macOS Sequoia: Following the same steps, when you return to full-screen mode, you need to clear the opacity before you can set it again.

Thanks!
