with the following js program: ``` y = 1 y += 2 y *= 3 console.log("hello, world") ``` I find that makepad says `can't find variable y` at the line containing "hello, world" If I type ``` y = 1 y += 2 y *= 3 console.log("hello, world") ``` The error is reported in the middle of the line containing `y *= 3` Both times I would have expected the errors to occur at the first occurence of y
