Radeon RX 7900 GRE USBC -> DP monitor modes do not match EDID info

Brief summary of the problem:

I'm currently running 3x 1440P monitors on a Radeon RX 7900 GRE. This ran fine prior to a recent update (also it runs fine if I use a LiveCD boot image as well). After a recent update, the monitor that is plugged in via the USB-C port cannot run 1440P (it tops out at 1080P). Swapping monitors across ports results in the same behavior for the monitor plugged in to the USB-C port.

Note, I ran the update March 8, but it included several weeks' worth of updates as I had neglected to do regular updates.

Hardware description:

• CPU: AMD Ryzen 9 7900X
• GPU (lspci): Advanced Micro Devices, Inc. [AMD/ATI] Navi 31 [Radeon RX 7900 XT/7900 XTX/7900M]
• GPU (GPUViewer): AMD Radeon RX 7900 GRE (RADV NAVI31)
• System Memory: 64GB
• Display(s): 2 x Dell U2713HM, 1 x NEC PA271W
• Type of Display Connection: 2 x DP, 1 x USB-C->DP

System information:

• Distro name and Version: Fedora 39 (was also a problem under 38 - I upgraded as a troubleshooting step)
• Kernel version: 6.7.7-200.fc39.x86_64
• Custom kernel: n/a
• AMD official driver version: n/a? I never installed a custom AMD driver, just whatever comes from repo maintainers
• Mesa Version: 23.3.5

How to reproduce the issue:

Currently, I have my NEC plugged in to the USB-C->DP port. When I run edid-decode /sys/class/drm/card1-DP-1/edid I get this result:

Take note that under Detailed Timing Descriptors, it's properly reporting "DTD 1: 2560x1440". However, when I run cat /sys/class/drm/card1-DP-1/modes

It does not list 2560x1440:

I'm unsure where to go next. Is this a driver bug? Do I need to play with a configuration file to make this work? I tried adding a custom kernel param via video DP-1:2560x1440@59.95 but that doesn't seem to do anything.
