Adapt HistoryTextWrapper#notifyListeners

[amartya4256]

This PR adapts the notifyListeners method in HistoryTextWrapper to call super#notifyListeners since not calling it changes the underlying default behaviour of its superclasses leading to faulty behavior, e.g. it breaks the chain of DPIChange processing leading to a broken drop down button in the HistoryTextWraper on DPIChange Event.

Bug Explained

When a file editor has the Ctrl+F search box open and the editor window is moved across screens with different DPI/scaling settings, the search box does not scale properly.

Steps to Reproduce:

1. Open a file in the editor.
2. Press Ctrl+F to open the search box.
3. Move the editor window from one monitor to another with a different zoom/DPI setting.
4. Observe that the search box remains the same size and does not adjust to the new DPI.

Reason

The class HistoryTextWrapper overrides the method notifyListeners:

@Override
public void notifyListeners(int eventType, Event event) {
	textBar.notifyListeners(eventType, event);
}

This method doesn't call super.notifyListeners(eventType, event), hence, the chain of DPIChange processing is broken, leading to the toolbar under the HistoryTextWrapper never scaling.
