Signpost: dragging an arrow into specific screen areas can crash and reset the game on some devices

[slavalamp]

Describe the bug
If you connect two non-numbered squares, long-press to see the possible predecessors of the smaller number one and drag its arrow into the notification or navigation bar, Signpost will crash and some of the progress will be reset if it didn't get autosaved

To Reproduce
Steps to reproduce the behavior:

1. Have full screen mode disabled, so that there is a notification bar always visible on the screen
2. Open Signpost
3. Connect some squares
4. Connect two non-numbered squares
5. Make sure the left/right click toggle is disabled (so long press = right click)
6. Long-press the smaller number non-numbered square (the one with a dot, "a" not "a+1") to see its possible predecessors
7. Drag it into the notification bar
8. Wait a second or two, the game will crash
9. Go back to Signpost and see your progress deleted

Expected behavior
Being able to drag the arrow all over the screen without crashes, like it seems to be possible to do with every other square and press types and combinations

Screenshots
i had a video recording but it seems i can't add one?

Version info (optional, but sometimes helpful)

• Phone/tablet model: Pixel 6a
• Android version: 15 (GrapheneOS)

This does not happen on Android 8 + Samsung Galaxy A3 (2017).

Just remembered I've got more info but never updated the issue. This kind of crash also happens when dragging a tile with a number in the same way, but the areas that cause a crash are different and don't even correspond to the system ui bars.

....just tested again and the thing doesn't happen to number tiles consistently anymore. So far I've had several tries where no crashes happened, one where only the bottom left corner caused the crash, one where it was only the top left corner, one where the crash area in the top left corner was big (probably mirroring the right areas on my screenshot). I have no idea what could be causing this.
