Brightness goes to max when I close MacBook lid with "sync brightness" option enabled

[igRo]

Before opening the issue, have you...?

• Searched for existing issues
• Looked through the wiki
• Updated MonitorControl to the latest version (if applicable)

Describe the bug

Brightness on the external display resets to 92..99% each time I close MacBook lid. In the office MacBook is always open, but at home I usually work solely on the external display and open my MacBook only when I attend video calls.

Steps to reproduce

1. Open MacBook
2. Connect external display
3. Set brightness to 65% (using the slider in the app OR system brightness slider on the touch bar)
4. Close MacBook lid

Expected behavior

Previously set brightness preserved

Anything else?

• "Sync brightness" enabled
• "Upon wake" is set to "read display", also reproduces for "apply last"
• When "upon wake" is set to "assume valid" - brightness in the app also updates to 100%, but previous brightness is preserved de facto until you move the slider
