Request a Copy does not work for old versions of versioned items

[engsterhold]

Describe the bug

(I am not sure if this is a DSpace or DSpace-angular issue)
When you activate the "Request a copy" feature for a bitstream by restricting the READ access of the bitstream to administrator or WITHDRAWN_READ for anonymous it leads to a login page instead of the "Request a copy" site if you use it on an old version of a versioned item. The main version works as expected.

The Access policies are equivalent:
Main version:

Old version:

The urls for the main item and the versioned item differs (local example, link probably not accessible)
Main version:
https://vhrz2249.hrz.uni-marburg.de/items/844af867-15b7-44dd-814a-978fb33cea60/request-a-copy?bitstream=1235b2f3-6f8d-418d-a1a3-42a11ce359f8

Old version:
https://vhrz2249.hrz.uni-marburg.de/bitstreams/b9567c49-6bc8-4d4b-b50f-00d4d4edbaf1/download

I am using DSpace 10, browser Safari / Chrome / Firefox
A short video demo (it shows a custom ui, but with the default ui the same happens, I have tested it local with the default ui)
First I try to download the old version (1), after that I switch to the new version (2)

To Reproduce

Steps to reproduce the behavior:

1. create an item
2. Restrict the access to a bitstream either by changing READ to administrator or set the anonymous access to "WITHDRAWN_READ"
3. Test if you get the "Request a copy" Proxy site when you want to download the bitstream.
4. Create a new Version for this item
5. The new / main version has default access settings
6. The old version has restricted access but leads to the login page instead of the "Request a copy" page
7. Changing the access settings for the latest / main item links to the "Request a copy" proxy site

Expected behavior

I would expect, that the old version also lead to the "Request a copy" proxy page.
