Unexpected behavior when passing `obj_names` to `SDSS.query_region()`

When using SDSS.query_region(), passing a list of names with the obj_names parameter does not perform as described in the documentation. The documentation says the names passed in will be repeated in the query result, but the names are not included in the resulting tables. A minimum working example is shown below:

from astroquery.sdss import SDSS
from astropy.coordinates import SkyCoord

# Define Source names and coordinates
names = ['Source1','Source2','Source3']
ra = [154.051772, 154.129982, 154.001069]
dec = [1.939617, 1.974458, 2.194234]
coord = SkyCoord(
    ra=ra, dec=dec, unit=['deg','deg']
)

# Perform Cross match
xids = SDSS.query_region(
    coord, 
    obj_names = names,
    radius = '2.0 arcsec', 
    spectro = True
)

This query results in the following table, which does not contain a column that indicates the matching input source name:

	ra	dec	objid	run	rerun	camcol	field	z	plate	mjd	fiberID	specobjid	run2d
0	154.052	1.93962	1.23765e+18	1907	301	3	210	0.0706007	502	51957	636	5.65377e+17	26
1	154.13	1.97446	1.23765e+18	1907	301	3	210	1.62504	502	51957	635	5.65376e+17	26
2	154.001	2.19423	1.23765e+18	1462	301	4	191	0.101115	502	51957	632	5.65376e+17	26

Having the capability to return the object names associated with each query is a very useful feature as it helps cut down on additional cross-matching that would be needed to associate each returned object with objects in the input coordinate list. I tried digging into the source code to identify a fix, but it was unclear to me how the obj_names parameter is being passed to the requests.request() function.

I am using python 3.11.9, astroquery v0.4.7 , astropy v6.1.0, and requests v2.32.2
