Yes, I reproduced on KDE6 + Qt6.7. This is a KDE only bug.

The & has a special meaning https://doc.qt.io/qt-6/qshortcut.html#details for mnemonic shortcuts.

By holding Alt, the first group tab is highlighted, while the others are not, Alt+Z will jump to the first tab.

The first tab will trigger this bug.

KDE automatically modifies the text string to include a & for mnemonic shortcuts, and we do & escaping, which makes the modification persist.

Escaping on GD's side goldendict/goldendict@ed2876d
