A weird bug in the preprocessor of PicoBlaze Simulator in JavaScript

[FlatAssembler]

A few days ago, I noticed that the "Download Hexadecimal" feature of my PicoBlaze Simulator doesn't work in WebPositive on HaikuOS. Which is bad not only because it makes my PicoBlaze Simulator much less useful on HaikuOS (WebPositive being the only browser on HaikuOS which supports enough JavaScript to run my PicoBlaze Simulator), but because it suggests that maybe it doesn't work in Safari either. Namely, both Safari and WebPositive are based on WebKit. The MacBook Air my grandmother bought me back in 2013 stopped working in 2021, so I cannot test that myself. I sent a Viber message to my mentor Ivan Aleksi about that, because he has a Mac in his office, but he is not responding to me.
