SUMMARY
After creating a folder and then trying to move a file/folder to that folder using the mouse, a drag selection box is shown instead.

STEPS TO REPRODUCE
1. Open a Dolphin File Manager
2. Navigate to a folder which has folders and files
3. Right click in a blank space and hover over the item "create new" until the sub menu appears
4. Select the  "Folder..." option
5. Enter a folder name or accept the default
6. Select the "ok" button
7. Hold the left mouse button on a file or folder and attempt to drag it into the newly created folder

OBSERVED RESULT
A drag selection box is created with the original right click point as the origin. 

EXPECTED RESULT
Clicking and dragging a file works as expected and no drag selection box is displayed after a folder is created

SOFTWARE/OS VERSIONS

Opensuse Tumbleweed 20240329
KDE Plasma Version: 6.0.3
KDE Frameworks Version: 6.0.0
Qt Version: 6.6.3

ADDITIONAL INFORMATION
This bug occurs regardless of the amount of files/folders in the directory, split panels are active or not, and on which file is chosen. I have tried to drag text files, videos, libreoffice documents, etc and all display the same behaviour. The first held left click on a file or folder after the new file dialog disappears will display a drag selection box.
