Since `index` is not undefined, this would indicate some sort of an internal inconsistency.
Hey, it's even better – all of the arrays in store.valueStore apparently consist only of varying number of undefineds.
And this is because ve.copyArray() is losing data, always returning an array of undefineds there.
And that is because #cloneNode is returning `undefined` for those elements (probably because they come from some weird dynamically-generated document). Which is clearly an Opera bug, but it'd be nice to work around it somehow.
I know why it only fails when debugging: because the fix in https://gerrit.wikimedia.org/r/#/c/61560/ is only applied when not debugging. Apparently the document there is *still* not a document evenif it appears to be one.
