BACK button no longer triggers the ZAP History menu

[IanSav]

In live TV pressing the BACK button no longer brings up the Zap History menu to allow selection of the previous channel to "zap" to.

Pressing BACK does nothing. It does not bring up the menu or trigger the Invalid Button icon. Pressing 0 does still zap to the previous channel.

Reproduction steps

Ensure that "MENU > Setup > TV > Zap History > Enable zap history" is enabled and that there are more than one entry permitted.

From live TV zap to a number of different channels so that there are valid contents for the Zap History menu then press the BACK button. Note that the Zap Menu is not displayed and neither is the Invalid Button icon.

Press 0 and note that the previous channel is selected.

BACK has been re-purposed to "show previously viewed channel" from being an alternative to PREV, and then doing nothing.
