Subject: fix: drag regions not working after navigation in WCO app
crrev.com/c/4814003 caused a regression where draggable regions (set
using the app-region CSS property) did not work after a Window
Controls Overlay or Borderless app navigated to another url.
This change fixes this issue by setting SupportsAppRegion to true on
each navigation within the app window.
