Canceled download keeps downloading in background

[Olympic1]

Background

CKAN Version:
The current development version

KSP Version:
1.5.1

Operating System:
Windows 10

Have you made any manual changes to your GameData folder (i.e., not via CKAN)?
Nope

Problem

What steps did you take in CKAN?

1. Download a mod
2. Cancel while it is downloading
3. Go back to Changeset tab

See that it keeps downloading the mod, even if it was canceled

What did you expect to happen?
That it stopped downloading the mod

What happened instead?
It kept downloading the mod. After it was downloaded, it shows up as a cached mod

Screenshots:

CKAN error codes (if applicable):
None

Yup, WebClient.CancelAsync does nothing. I thought this was mentioned in some other issue a while back but I can't find it now.

Would #2418 fix this situation?

[HebaruSan]

I think that one cleans up some GUI quirks without affecting the underlying download code. It would still continue a cancelled download, it would just look better doing it.

As far as I remember #2418 would not have fixed this, as that was mostly GUI stuff, right.
Edit: I redid #2418 in #2602 , but that changes nothing regarding this issue.

Found the previous mention, it was a forum post:

In my testing on Windows for #3635, I saw downloads seemingly cancelling. Closing as it no longer seems to happen (maybe some bug fixes in .NET?).
