Loss of the API after a debug refresh (F6)

[swfsql]

When ovrt is fresh started, it does have access to the APIs, such as window.SpawnOverlay.

Example of when an overlay is opened and no errors are shown on the console:

init main
ovrt_sys.js:319 calling spawn_overlay
ovrt_sys.js:322 transform_str: {"posX":0.0,"posY":0.0,"posZ":0.0,"rotX":0.0,"rotY":0.0,"rotZ":0.0,"size":0.25,"opacity":1.0,"curvature":0.0,"framerate":60,"ecoMode":true,"lookHiding":false,"attachedDevice":0,"shouldSave":false}
ovrt_sys.js:322 called spawn_overlay. Uid: 0
ovrt_sys.js:325 event overlay_opened. Uid: 900
ovrt_sys.js:325 event interaction_state_changed. is_interacting:  false

But when F6 is pressed and the custom app is reloaded, no window is opened, and the console shows:

init main
ovrt_sys.js:319 calling spawn_overlay
ovrt_sys.js:322 transform_str: {"posX":0.0,"posY":0.0,"posZ":0.0,"rotX":0.0,"rotY":0.0,"rotZ":0.0,"size":0.25,"opacity":1.0,"curvature":0.0,"framerate":60,"ecoMode":true,"lookHiding":false,"attachedDevice":0,"shouldSave":false}
ovrt_sys.js:293 Uncaught (in promise) TypeError: window.SpawnOverlay is not a function

I expect that some rewiring is needed when refreshing the custom app, since it loses the API functions.
