Missing button

[AuracleTech]

The gallery button acts as a child button There is no child button, only a parent button But then the gallery button becomes a child if the hierarchy of edits is long

Odd behavior

I recommend adding a Child next to the Parent button and make the gallery only return to the gallery

@mrdoob this behavior was changed in 0c48c11c and 7da77505. I don't really know the rationale to convert it to back button. Back is always available using the browser buttons.
