Android Gboard multiline input from keyboard clipboard places selection at wrong place

[deep-wonder]

Steps:

1. Open https://prosemirror.net/ in chrome
2. Type a multiline message in the editor (press enter for new lines)
3. Select all content and Cut/Copy
4. Use the clipboard (present above the keyboard) to insert the content
5. Notice cursor is at wrong position, the placement of cursor depends on number of lines.

This problem appears to be in GBoard, not ProseMirror. If I do something like it in a plain contenteditable element (<div contenteditable=true><p><br></p></div>) I see the cursor in the wrong place as well.
