1. Please describe the problem:
In the last week or two, I noticed that Shift+PgUp and Shift+PgDn don't work in a VT in F33 and Rawhide. On further investigation I find that Ctrl+Shift+UpArrow and Ctrl+Shift+DownArrow don't work either. Testing the three most recent F32 stable kernels, I find that with kernel-5.8.9-200.fc32.x86_64, Shift+PgUp and Shift+PgDn work in a VT, but Ctrl+Shift+UpArrow and Ctrl+Shift+DownArrow do not. In kernel-5.8.10-200.fc32.x86_64 and kernel-5.8.11-200.fc32.x86_64, none of the four key combos work in a VT. All four key combos work fine in graphical mode, however.

I tested this on 2 different F32 machines with the same 3 kernels installed and the behavior was exactly the same on each kernel.

2. What is the Version-Release number of the kernel:
5.8.9-200.fc32.x86_64 (2 out of 4 broken)
kernel-5.8.10-200.fc32.x86_64 and kernel-5.8.11-200.fc32.x86_64 (all 4 broken)

I'm afraid that there is nothing we can do to fix this.

Upstream has decided to drop the scrollback buffer support due to there being various bugs and no active maintainer to fix them, see e.g. : https://www.phoronix.com/scan.php?page=news_item&px=Linux-5.9-Drops-Soft-Scrollback

And apparently the bugs were serious enough that the dropping of the scrollback support has been backported to the 5.8.y stable series, see: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/log/?h=linux-5.8.y

So yes it is gone; and unless someone steps up to rewrite and submit a new version upstream it will stay gone, sorry.
