Errors in component constructors do not bubble to the top

[curran]

(original comment by @FriendFX on #64):

If the execution of a plugin's "constructor" fails (e.g. due to a reference error), the error gets caught at line 1460 of chiasm-v0.3.0.js (I think it is now line 254 in index.js) and even though it gets rejected there, it doesn't propagate to the top - there is no message in the console.

BTW, I am using Firefox 43.0.
