No progress bar during file upload using Microsoft Edge

[Goore25]

Steps to reproduce

Just use Microsft Edge for uploading file to Nextcloud server.
I tired with:
Win10 (Creators Fall Update 1709, build 16299.19) and MS Edge 41.16299.15.0 (EdgeHTML 16.16299)
Win10 (1703, build15063.726) and MS Edge 40.15063.674.0 (EdgeHTML 15.15063)

Expected behaviour

Progress bar should show the upload status graphically

Actual behaviour

There is only text message for wating xxx minutes or a few seconds

For me there is a upload bar on master (upcoming 13):

Seems to be related to 12. There is only a "Uploading...". I would close this as fixed in 13, because we did some restructuring of how the upload works now and not backport this new feature.

Hi, I tried today with version 13.0.0.6 (13.0.0 Beta1 from 3.12.2017 - Daily) and there is no progress bar in MS Edge again...
Tested on Win10 (Creators Fall Update 1709, build 16299.19) and MS Edge 41.16299.15.0 (EdgeHTML 16.16299)
