jQuery Mobile not loading on FileMaker Go Webviewer

[typewriter]

I use jQuery and the jQueryUI slider widget to display a slider in FileMaker Pro (v17-17-18-19). Works fine but I also need to have it work on FileMaker Go, so I tried my luck on jQuery Mobile 1.4.5. The slider is working nicely on FileMaker Pro, but on FmGo 17, 18 or 19 it doesn't load, keeps displaying a spinning logo. When I publish the HTML page on a website and open it in Safari Mobile it works fine. Any help appreciated! See the example file: just downlaod it and open it on FMGo. The Webviewer and the HTML are displayed side by side.
