The custom skin must get saved in the game, in the section of Owned Skins in the dressing room, but it's not happening anymore.

Steps to reproduce:

1) Open the Dressing Room.
2) Open the Create character/edit character.
3) Go to the Classic Skins section.
4) Go to Owned skins.
5) Tap on Choose New Skin.
6) Then import a skin to minecraft.

Observed Result:

The custom skin gets imported in the game but doesn't gets saved in the Owned Skins section, and after tapping on the Owned Skins the newly imported skin is gone.

Expected Result:

The custom skin must get imported and get saved in the game as well, and tapping on the Owned Skins will not remove the custom skin but rather work as anytime whenever we wish to switch to custom skin.
