bug: Not hydrating in iOS 10

[tricki]

Stencil version:

 @stencil/core@1.7.2

I'm submitting a:

[x] bug report
[ ] feature request
[ ] support request => Please do not submit support requests here, use one of these channels: https://stencil-worldwide.herokuapp.com/ or https://forum.ionicframework.com/

Current behavior:
No components get hydrated.

Expected behavior:
Components get hydrated.

Steps to reproduce:
Open app in Safari on iOS 10.

Other information:
After some digging I found that the nomodule script (app.js) is being downloaded, but not the type="module" script (p-********.js). app.js only runs to this line, which evaluates to false:

    // Safari 10 support type="module" but still download and executes the nomodule script
    if (!currentScript || !currentScript.hasAttribute('nomodule') || !('onbeforeload' in currentScript)) {

Just found #1900 which describes the same bug in the comments. Feel free to close this issue if the discussion should take place there.

we decided to use the "loader" variant. we raised from 1.3.0 -> 1.7.0 and all our safari 10 user can't use the page now.

see: #1900 (comment)

cheers

btw safari 10.0 on ios has a old webkit.performance api https://developer.mozilla.org/de/docs/Web/Web_Components

and breaks silently at performance.mark(), performance.measure & performance.getEntriesByName

to get rid of use stencil build --no-profile
