QML ColorDialog uses TextField.copyAll() which doesn't exist to copy the color

When clicking on the "copy button" of the QML ColorDialog, it tries to copy the value of the TextField by calling the "copyAll()" function on it. This function does not exist though (according to documentation and the error message).

Error message: file:///home/kilian/Qt/5.15.2/gcc_64/qml/QtQuick/Dialogs/DefaultColorDialog.qml:385: TypeError: Property 'copyAll' of object TextField_QMLTYPE_13(0x55abeda2f000) is not a function

I put the QML file used (the rest of the project is the default from a new project) as attachment if you want to use it.
