amp-selector 1.0 renders nothing on playground and on chrome on iOS

### Description

I tried amp-selector 1.0 on the playground and it renders nothing on the screen, when I switch to version 0.1 it works and I can see the options on the screen.

The same code is working on my device (Linux) with chrome, but my teammate who has iOS only sees a white screen (just like in the playground).

### Reproduction Steps

I use these scripts :
```


```
and this simple code :

```

```

The result is a blank page.

Please look at this [playground](https://playground.amp.dev/?format=websites&_gl=1*1ui0nrr*_ga*YW1wLVg2T3hrazFBWW5YSjNnLUZzS0JnNUE.&mode=Responsive#share=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)

When you change the amp-selector script to the version 0.1 you should see correctly the options :

### AMP Version Affected

Start by reproducing the blank page in the linked AMP Playground using amp-selector-1.0.js, then compare it with amp-selector-0.1.js in Chrome on iOS. Inspect the amp-selector component entry point and its existing tests, if available, to identify the version-specific failure. Done means the supplied selector renders both options on the affected setup without regressing version 0.1 behavior.
