Description

The following exception is thrown when launching a Windows 8.1 app on Windows 10:

Exception is about to be caught by JavaScript library code at line 2083, column 9 in ms-appx://com.test/www/cordova.js

0x80070490 - JavaScript runtime error: Element not found.

This occurs due to the addition made in https://issues.apache.org/jira/browse/CB-12238. The check isn't sufficient to account for the use case described above.

I believe this to be the solution:

// Make title bg color match splashscreen bg color
function colorizeTitleBar() {
    var appView = Windows.UI.ViewManagement.ApplicationView.getForCurrentView();
    if (appView.titleBar && (isWin10UWP || isWp10)) {
        titleInitialBgColor = appView.titleBar.backgroundColor;

        appView.titleBar.backgroundColor = titleBgColor;
        appView.titleBar.buttonBackgroundColor = titleBgColor;
    }
}

// Revert title bg color
function revertTitleBarColor() {
    var appView = Windows.UI.ViewManagement.ApplicationView.getForCurrentView();
    if (appView.titleBar && (isWin10UWP || isWp10)) {
        appView.titleBar.backgroundColor = titleInitialBgColor;
        appView.titleBar.buttonBackgroundColor = titleInitialBgColor;
    }
}
