width shrinked to zero on some Android Devices

[abarcellona]

I have deployed an app that uses iscrollview. It works fine on most Android 2.3 and 4+ devices except on some (example Haipai N7102 with Android 4.2.1) where the pop-up using iscrollview is displayed as a "grey vertical line" (width=0).
I already have in my css:

.iscroll-scroller {
width:100% !important;
}

It seems an issue with native webview of some chinese smartphones. using Chrome on the same device works fine.

This is also needed for Chrome desktop. Otherwise, list width is limited. (doesn't fit page width)
