Bug Choice Overrides using Ezandora-Choice-Override render incorrectly

[VeeArr]

Starting in r28944, relay browser choice overrides powered by Ezandora's Choice Override script do not render correctly. Instead of redirecting to a blank page and rendering on top of that, the UI for the choice renders directly over the inventory. Tested in multiple browsers, with the same outcome. Examples of what it looks like attached.

I'm not sure if this is something that was overlooked in the changes in r28944, or something that now needs to be fixed in Ezandora's Choice Override script to account for these changes.
