BUR #35431 has failed.
rename steamed_egg -> chawanmushi_(steamedeggz)
rename chawanmushi -> chawanmushi_(zukka5187)
rename chawanmushi_(food) -> chawanmushi
create alias steamed_egg -> chawanmushi
These two artist tags is ambiguous with chawanmushi (steamed egg), the latter tag in particular is the reason why the food tag currently have to use "(food)" qualifier despite the artist is naming themselves after it.
So the solution is to rename both tags with qualifier. Since both artist coincidentally uses the exact same preferred username of "chawanmushi", they will have an alias based on their other handles. Also aliasing "steamed egg" to "chawanmushi" for utility purposes.
