NumPad button attempts to clear puzzle
Initial conditions:Android KitKat smartphone.
Browser: Chrome or UC Browser (reproduced in both)
Signed in: doesn't matter
Puzzle:
http://www.calcudoku.org/en/2017-06-30/10/3Size: medium?.. (couldn't reproduce bug with small size)
NumPad position: left
Puzzle must not be empty (just a couple of digits will do).
That's what I do:
1. Press the NumPad button.
Now the buttons are at the bottom.
2. Press the NumPad button again.
The buttons move to the right,
and a window pops up asking if I want to clear the whole puzzle.
Sometimes it's vice versa: the window pops up, I press “Cancel”, and
then the buttons move to the right.
So far, I could not reproduce this bug with smaller puzzles (i.e. 6×6), nor does it show up in the non-mobile version of the site.
