Interesting peskiness with smileys

I attempted to add :stuck_out_tongue: to a post today, and it took several tries to make it work; apparently, :stuck_out_tongue: (with an upper-case P instead of a lower-case one) doesn’t work while :stuck_out_tongue: does.

Would it be possible to make that smiley non-case-sensitive?

All set. :stuck_out_tongue: :stuck_out_tongue:

It’ll show twice in the smiley drop-down though …
