EXPECTED RESULT
The item is dragged as when using a mouse

ADDITIONAL INFORMATION

Dolphin version 24.05.0

Enabling touch mode on my tablet, so it functions as a touchpad, and then using my hand does work correctly. This issue seems specific to using the tablet pen.

I can change the Zoom, and I can re-order tabs with a tablet pen.

I think this could an issue in qt itself.

After reproducing the problem on neon unstable and adding some logging, I found that both tablet and mouse behaved the same up until dolphin executes the QDrag. However when using a tablet pen, Dolphin doesn't receive any subsequent drag events.

I then tried the drag and drop examples qt provides (https://code.qt.io/cgit/qt/qtbase.git/tree/examples/widgets/draganddrop?h=6.7) and got the same results, where dragging only works with a mouse and not a tablet pen.
