Is your feature request related to a problem? Please describe.

NVDA uses legacy focus redirection code in several places. For example:

• NVDAObjects.IAccessible.qt.Container
• NVDAObjects.IAccessible.qt.Client
• NVDAObjects.UIA.edge.EdgeHTMLRootContainer

The Edge code looks like this:

	def event_gainFocus(self):
		firstChild=self.firstChild
		if isinstance(firstChild,UIA):
			eventHandler.executeEvent("gainFocus",firstChild)
			return
		return super(EdgeHTMLRootContainer,self).event_gainFocus()

Describe the solution you'd like

NVDAObjects now support the new focusRedirect code. The code above could therefore be shortened and simplified to the following:

	def _get_focusRedirect(self):
		firstChild=self.firstChild
		if isinstance(firstChild,UIA):
			return firstChild
		return None

Describe alternatives you've considered

There is always a possibility to leave this as is.
