Comment (by mmezzarobba):
Also, like in the case of #17151, I think having:
{{{
sage: legendre_P(0, x).parent()
Integer Ring
sage: legendre_P(0, SR(1)).parent()
Integer Ring
}}}
is a bug.
Compare for example:
{{{
sage: sin(0).parent() # not sure I like this, but somehow makes sense
Integer Ring
sage: sin(SR(0)).parent()
Symbolic Ring
}}}
