BUG: Fix DataFrame constructor misclassification of array-like with 'name' attribute
Previously, any object with a
.name
attribute (like somevtkArray
-like objects) was assumed to be aSeries
orIndex
, causing the DataFrame constructor to misinterpret the input and raise errors when passed valid 2D array-likes.This fix ensures we only apply the named-Series/Index logic when the input is actually an instance of
ABCSeries
orABCIndex
, and thename
is notNone
.A new test was added to ensure array-like subclasses with
.name
are handled correctly.DataFrame
