[Boot2Qt] Context menu actions not applying to previously modified text in Textarea

MacOS 15.3.2

Qt Creator 16.0.0

RPi4 with Qt 6.9.0RC2

Steps to reproduce:

1. Open sample application with TextArea.
2. Type some text into the textarea.
3. Select a portion of the text.
4. Right-click to open the context menu.
5. Choose an action (e.g., Copy the selected text).
6. Keep the text selected and right-click again to open the context menu.
7. Choose another action (e.g., Delete or Cut).
8. Observe that the action is not applied, and the selected text remains unchanged.

Sample app:

import QtQuick
import QtQuick.ControlsWindow {
    width: 640
    height: 480
    visible: true
    title: qsTr("Hello World")
    TextArea {
        text: qsTr("TextArea\n...\n...\n...")
    }
}

Note: It's not reproducible on desktop (both macOS and Linux) and also does not happen with TextField.
