Describe your issue

With any theme other than the default "Dark" theme is selected, the changes are not reflected within the Settings window. The main/chat window immediately reflects the change in theme. The issue continues after quitting and restarting after choosing the theme.

This is a UX usability issue for users who have difficulties reading light text on dark backgrounds, particularly those with dyslexia or astigmatism.

I verified that the value is truly set in ~/Library/Application\ Support/chatterino/Settings/settings.json:

"misc": {
    "currentVersion": "2.4.5",
    "lockNotebookLayout": false,
    "beta": true,
    "restartOnCrash": true
},
"appearance": {
    "theme": {
        "name": "Light"
    },
    "currentFontFamily": "SF Mono Square",
    "currentFontSize": 10,
    "showTabCloseButton": false,
    "hidePreferencesButton": true,
    "hideUserButton": true,
    "messages": {
        "separateMessages": true,
        "alternateMessageBackground": true,
        "hideModerated": true,
        "showTimestamps": true,
        "timestampFormat": "hh:mm"
    },
    "splitheader": {
        "showUptime": true,
        "showGame": true,
        "showTitle": true
    },
    "uiScale2": 1.200000047683716,
    "tabDirection": 2
},

This isn't a bug there just isn't code for this window to respect the Theme setting, this was the case with many other windows until neri started implementing them #4423 #4671 #4817
