This is similar to this much older issue: HTML file input with multi selection in UIWebView not working for videos
This is NOT a duplicate of this: iOS update to 10.3.1 breaks HTML input element
I have tested this on my app that was working, on versions going back 45 days, it seems iOS 10.3.1 changed the file input and now there is the multiple video selection, without the "compressing" stage that occurred after selection and before switching out of the interface. Tested on iphone 6S.
When access the the video file via javascript, there is no size or content (compare to image at the bottom, which works): http://i.imgur.com/ms2hSiG.png
