Bug 2445056

Even though the KeePassXC version hasn't changed, AutoType is randomly "pasting" upper-case symbols (both capital letters and the "shifted" symbols above them on their keys) in both the username and password fields as lower-case.  For example, an H might get Autotyped as an h, or a $ might get Autotyped as a 4.  This happens regardless of the source username/password or target (browser or other app).  When using it to sign into documents and sites, this results in a large percentage of invalid login attempts.

Using the copy username/password process in KeePassXC and manually pasting to the target still works fine.

This started with the Bazzite upgrade from version F43.20260217 to F43.20260303.  Unfortunately, I don't know what the upstream Fedora versions changed to.  The Bazzite people say they just use whatever comes down from Fedora.  So, I loaded up the latest Fedora distribution in a Virtual Machine Manager VM and fully updated it. I installed the same (latest) KeePassXC flatpak as I use in Bazzite. The problem exists there as well. 

Reproducible: Sometimes

Steps to Reproduce:
1.  The easiest way to reproduce this is to Autotype into a word processing document (but you can do it anywhere else --like a browser).
2.  Open a blank document and repeatedly hit your Autotype key combination (mine's CTRL-ALT-A).  You might have to hit ENTER to get each "paste" on its own line.  Just pick the same username/password entry from the KeePassXC data base each time.
3.  Note that the Autotyped strings are not necessarily the same.  I've had erroneously lower-cased symbols happen 1/3 to 1/2 of the time.
Actual Results:
A large percentage of Autotyped entries will randomly contain upper-case symbols that show up as lower-case.  If you're trying to log in with those values, you'll get an invalid login attempt.

Expected Results:
The Autotyped values should exactly match what's in the data base.  There should be no random conversion from upper-case to lower-case and logins should work.

Additional Information:
For my Fedora VM tests:
- Linux Fedora 6.18.13-200.fc43.x86_64-bit
- KDE Plasma Version:  6.6.1
- KDE Frameworks Version:  6.23.0
- Qt Version: 6.10.2
- Graphics Platform:  Wayland
- KeePassXC Flatpak 2.7.11
- Flatseal has Environment Variables SSH_AUTH_SOCK=$SSH_AUTH_SOCK and QT_QPA_PLATFORM=xcb

I've reported this to both KeePassXC and Bazzite.  In case it helps, here are the bug reports there:
