Ask for confirmation before auto-deleting an invalid polygon

[getkey]

The editor should warn you that if you unselect this polygon, it will be destroyed since it's invalid. But you will also be given the option to cancel to keep your invalid polygon selected so you can fix it.

Unselecting this polygon will remove it because it is invalid. Are you fine with that?
[Cancel] [OK]

More context: WMGX on Discord

Maybe I can help, where is the file responsible for this?

Gladly!

Here is the code that handles mouse events and updates the selection based on the selection box.

ble/src/epics/select.ts

Line 223 in 34ae3a3

store.editor.setSelection(entitiesToAdd);

What I would do:

1. for each element that's in the old selection but not in the new one
2. if one of them is invalid (entity.params.isValid is false)
3. show a popup (alert() is fine)
4. if Ok -> continue normally
5. if Cancel, use store.undoManager.stopGroup(); store.undoManager.undo(); to revert to the old selection box
