Pull Request Overview

This PR refines the background’s resize handling by always wiring up resize events in the constructor and consolidating conditional redraw/scale logic.

• Adds an unconditional RESIZE event listener in the constructor to trigger draw and scale services.
• Refactors the per-frame check to a single combined width/height comparison block.
• Updates package versions in both the template’s package.json and the root package.json.

• No tests appear to cover the new resize handling logic; consider adding unit tests or integration tests to verify that backgroundDrawService and backgroundChangeScaleService are invoked correctly when the stage is resized.

backgroundDrawService(this);

• Consider reintroducing a check like !stage.hasEventListener(Event.RESIZE) before adding the listener to prevent registering duplicate handlers and potential memory leaks.

stage.addEventListener(Event.RESIZE, () =>

[Copilot]

Add a null check or guard to ensure stage is defined before calling addEventListener, e.g. if (stage) { ... }, to avoid potential runtime errors.

Suggested change

	stage.addEventListener(Event.RESIZE, () =>
	{
	backgroundDrawService(this);
	backgroundChangeScaleService(this);
	});
	if (stage) {
	stage.addEventListener(Event.RESIZE, () =>
	{
	backgroundDrawService(this);
	backgroundChangeScaleService(this);
	});
	}

[Copilot]

Current order calls backgroundDrawService before backgroundChangeScaleService, which may draw at the wrong scale. Swap these calls so scaling happens before drawing.

Suggested change

	backgroundDrawService(this);
	backgroundChangeScaleService(this);
	backgroundChangeScaleService(this);
	backgroundDrawService(this);
