Description
- comments of pages after the first one are added at the bottom instead of replacing comments from the previous page, so that, e.g.: after 4 pages you have four copies of the comment boxes, each retaining the text you previously input.
probably because you never empty the div before .appendChild

for (var element of audioEngineContext.audioObjects)
I am not pushing this to the repo yet, because I am not sure if you are referencing the content of commentHolder anywhere else, which could lead to a memory leak. Have a look at it and then feel free to merge in.

The comment boxes are managed by the interface object in core.js (so we don't reinvent the wheel for each test page). Likely it is never getting called to scrub the boxes.

Yes I know, but there are more things behind it that I'd rather fix that's all. Since it is a global object, if it is cropping up here it could crop up else where

Fixed in dev_main. The InterfaceContext object now explicitly removes the node from the page, then destroys the object on each page reload.
