I can confirm ZONESTAR_LCD buttons are not working in Bugfix 2.0.x, yet work fine in release version 2.0.7.2

Using a test setup (ramps + 2004 lcd + DIY keypad) I was able to confirm that 2.0.7.2 works as expected, but bugfix only the center button works (sort of)

Seem to have been broken in commit f6ffbe5
Sadly this is a huge commit.

Error is in Marlin/src/lcd/marlinui.cpp
if (TERN0(REPRAPWORLD_KEYPAD, handle_keypad()))
should be
if (TERN0(IS_RRW_KEYPAD, handle_keypad()))

PR to fix this has been created.

I don't even have this type of LCD, had to make my own compatible one.
