thanks for reporting! there's a library included in this project to prevent infinite loops from crashing the editor, which should prevent this. however, i noticed that

for (var i = 0; ;) {

}

is caught and stopped by the loop-protect code, but

for (let i = 0; ; ) {

}

is not caught and handled by the loop protect code.

i was looking at the loop-protect library and it seems like the version that i made the fork from (jsbin/loop-protect) has updated the project a lot, and i think it would make sense for this project to switch from the fork i made to the jsbin library. i also just tested the two for loops on jsbin, and it seems to catch the infinite loop for both of them, so this gives me confidence that this change would fix this bug.

i started to work on this, following the instructions here, but keep getting the following error from Babel: cannot read property 'registerPlugin' of undefined. for some reason when i do import Babel from '@babel/standalone';, Babel is still undefined.

switching this to high priority—seems like it's causing a lot of bugs and frustration.
