Commentary
The Ugric etymology is phonologically irregular, as Hungarian z does not correspond regularly to Khanty and Mansi *ć. The origin of Khanty retroflex ḷ is also unclear.
UEW notes that the Khanty vocalism is irregular and attributes this to influence from the word-internal palatal *ć. Further research is needed on this issue, but as a large part of the vocabulary shared by Khanty and Mansi shows irregular sound-correspondences, it is possible that these Ob-Ugric words are not real cognates.
Conclusion
The Ugric etymology should be rejected as phonologically irregular.
