Setting to reproduce:
Set Network -> Connections -> Outgoing peer connection encryption to Encrypted only.

Current behavior:
The setting only applies to Bittorrent peers.

Expected behavior:
It (or a separate setting) should apply to HTTP peers aka. WebSeeds defined in the url-list field (BEP 19).
HTTP-only WebSeeds should be tried on HTTPS or ignored.

If Outgoing peer connection encryption is set to Encrypted preferred, HTTP-only WebSeeds should be tried on HTTPS first,
then fall back to HTTP while sending the Upgrade-Insecure-Requests HTTP header.

Example public torrent with a few non HTTPS WebSeeds defined:
