AMP-LIST AMP-SELECTOR LIMITATIONS

## What's the issue?

Seems like there is a limit to how many selectors/togglers you can have in an amp list. In the examples below I have roughly 40 buttons on the page as options and sub options. On number 36 click (chicken quesadilla -> Rice -> Roasted Corn) the data does load but only partially and then any of the the options > 36 don't select at all.

See fiddles and dev site below.

Any ideas on why this is happening. I have a couple products that a lot of sub options. This type of behavior is happening on both instances and starts on the same count number of selectors.

## How do we reproduce the issue?

Link 2: Bugged data from link 1 isolated and working. Including to show that its not a data issue. https://jsfiddle.net/9vkyztb3/

## What browsers are affected?

All

## Which AMP version is affected?

https://cdn.ampproject.org/v0.js
https://cdn.ampproject.org/v0/amp-list-0.1.js
https://cdn.ampproject.org/v0/amp-selector-0.1.js
https://cdn.ampproject.org/v0/amp-mustache-0.2.js

- I also tried reverting back to 0.1.js on amp-mustache and still got the same issue.

Start by reproducing the selector limit using the three linked JSFiddle and website examples, focusing on the 36th option and the listed amp-list, amp-selector, and amp-mustache versions. Then trace the relevant AMP component entry points and tests to identify the expected behavior and document a passing regression case for options beyond that count.
