Dragging map canvas does not work with Bluetooth mouse

[JuhoErvasti]

What is the bug or the crash? What were your expectations and what actually happened?

Attempting to drag the map with a Bluetooth does not work at all. Otherwise using the mouse works.

@JuhoErvasti , thanks for the report. Before we investigate this further, could you try a development build to confirm whether this is still a problem there? The next version of QField comes with the latest Qt 6.9 version, which did fix some issues with regards to the pointer device handlers. If we're lucky, this is already fixed :)

You can test an APK here: https://github.com/opengisch/QField/pull/6817#issuecomment-3555100368 .

@nirvn I tested it with the APK, but unfortunately the issue persists.
