It's what combobox does when it makes an empty list.
There's an open merge request to fix this at https://invent.kde.org/plasma/xdg-desktop-portal-kde/-/merge_requests/419
I looked into fixing the styling in the ComboBox component when it has an empty drop-down. There's logic in the Breeze QStyle to disable the arrow button when the drop-down is empty: https://invent.kde.org/plasma/breeze/-/blob/master/kstyle/breezestyle.cpp?ref_type=heads#L7717 However it would appear this doesn't come across the style bridge for the QML version.
(In reply to Nate Graham from comment #2) > There's an open merge request to fix this at > https://invent.kde.org/plasma/xdg-desktop-portal-kde/-/merge_requests/419 seems completely unrelated?

ComboBox: Disallow opening empty comboboxes Don't let the user open a combobox which has zero items in the popup. Unfortunately there isn't dedicated api for that and the popup has to be dinamically assigned or unassigned, but it works well. the arrow won't yet change its look, as it needs adjustment in Breeze together with https://invent.kde.org/plasma/breeze/-/merge_requests/554 M +5 -1 org.kde.desktop/ComboBox.qml https://invent.kde.org/frameworks/qqc2-desktop-style/-/commit/e7fbca2734afb753bc44c08335955c0448971c48

Re-opening as the commit has to be reverted because it caused regressions worse than the original issue. https://invent.kde.org/frameworks/qqc2-desktop-style/-/commit/e5eef9ab76ff3a76a0327459239b68d6d7da4daf
