From: Dongwon Kim
Subject: [PATCH 1/3] ui/gtk-egl: un-tab and re-tab should destroy egl surface and context
Date: Fri, 2 Jul 2021 17:28:07 -0700

An old esurface should be destroyed and set to be NULL when doing
un-tab and re-tab so that a new esurface an context can be created
for the window widget that those will be bound to.
