cordova-plugin-camera file picker does not appear in browser

Using latest (5.3.3) Cordova and cordova-plugin-camera 1.2.0, browser support to select an image is not working. Each time you call navigator.camera.getPicture with sourceType = Camera.PictureSourceType.PHOTOLIBRARY a new file input is appended to the document, but nothing actually happens.

Tested on Chrome 46 and Firefox 40.

To reproduce, create a basic Cordova project. Add browser as a platform then add the cordova-plugin-camera plugin. Then add a button to your document which when clicked executes the following:

navigator.camera.getPicture(success, error, {
sourceType: Camera.PictureSourceType.PHOTOLIBRARY
});

(include a suitable success/error handler).

Run with cordova emulate browser. When the above is executed, the following is inserted into your document:

<input type="file" name="files[]">

Successive calls will add more of these. If you actually click on one then the file picker will appear. But it seems that whatever simulates this click is not working.
