If of any use, I can confirm that this doesn't occur on:
Name : steam Version : 1.0.0.85 Release : 1.fc43 Architecture: i686 Install Date: Thu 30 Oct 2025 20:55:02 GMT Size : 20396328 Signature : RSA/SHA256, Fri 24 Oct 2025 13:31:36 BST, Key ID 6a2af96194843c65 RSA/SHA256, Fri 24 Oct 2025 13:31:35 BST, Key ID 6a2af96194843c65 Source RPM : steam-1.0.0.85-1.fc43.src.rpm Build Date : Fri 17 Oct 2025 13:58:21 BST Build Host : buildvm-07.virt.rpmfusion.net Packager : RPM Fusion Vendor : RPM Fusion Bug URL : https://bugz.rpmfusion.org/steam

…so I'll presume that you're not utilising kwin-6.5.4-2.fc43.
Actually, @Buggem, I can reproduce this: It solely reproduces when one invokes devtools:// via //div[@class="_1n7Wloe5jZ6fSuvV18NNWI contextMenuItem"]/text()="Inspect Element":
https://github.com/user-attachments/assets/504db229-6944-41c8-b99e-ee102aa2eb52
If one, instead, invokes it via -dev's SupportsGroup(ContextMenuContentType::ITEM_GROUP_PRINT), the context menu is also GTK-based, and correctly placed.
Nothing extracted yet.
Your system information
I have tested it on two devices, I'll list both here.
