Chasing down a bug exclusive to HTML5 export

Still trying to resolve the last major known bug which causes the game to not detect that all blocks have been placed and to spawn the next one. Seems to only occur on HTML5 exports, yet not on the debug HTML5 version on my machine.

I'm thinking [hoping] it's an issue with how godot triggers timers [I've isolated the issue to this section of my code], so I've changed the mode from 'idle' to 'physics'.
