Redirects fails proxy authentification

[vvmikheev]

request to http://google.com via Proxy fails with 407 Proxy Authentication Required after redirect to http://www.google.com.
I can not provide a proxy to build a MRE. But here are some logs.

[2024-03-14T09:20:06Z DEBUG reqwest::connect] starting new connection: http://google.com/
[2024-03-14T09:20:06Z DEBUG reqwest::connect] proxy(mysuperproxy) intercepts 'http://google.com/'

Status code: 407 Proxy Authentication Required

As far as I understand PendingRequest seems to lose Proxy-Authorization header during redirect.
