Espruino is a JavaScript interpreter for low-power Microcontrollers. This site is both a support community for Espruino and a place to share what you are working on.

Yes, while it looks sensible, what you did in fact does not makes sense in event based system like espruino. The while block is useful only for short code that finishes quickly and not with true condition and not with any wait inside.
Your blocks would translate well to e.g. micropython. Yes it is confusing and your case perfectly shows how those blocks are hiding the true nature of event based javascript and Espruino. The first generated code is in fact complete nonsene, which is not your fault. Your fix is well meant but not really helping, check e.g. this explanation
Maybe the block->code generation could be much smarter to create illusion that this works but it looks like currently it is not clever enough.
