(iOS 11.2.5) apple-mobile-web-app-capable breaks <input type=“file”> workaround?

Question

iOS 11.2.5 has broken the image capture button <input type="file"> for home screen (launch) icon, running in standalone mode (web capable mobile apps)...

Test case:- capture.html

<meta name="apple-mobile-web-app-capable" content="yes">
<input type="file">

To reproduce :

open capture.html in mobile safari, add to home screen, then open from home screen icon. Press choose file, select camera.

Camera opens with just a black view.

If I open capture.html in mobile safari (not from home screen icon) and use camera, it works.

If I remove apple-mobile-web-app-capable from capture.html and repeat the process of adding a home screen icon, the camera works correctly.

Question :

Does anyone have a workaround for this issue whilst retaining standalone mode (which is essential for a mobile app)?

EDIT

Logged as a bug with Apple (id 36820143), who have since closed it CLOSED DUPLICATE OF 35542231:CLOSED . So hopefully it will be fixed in the next update (fingers crossed).

This has now been fixed in iOS 11.3 beta 1. :)
